OPINION OF THE COURT
WILLIAM A. NORRIS, Circuit Judge:In 1988, Alexander E. Moskovits was convicted by a jury of various narcotics offenses related to the possession and distribution of cocaine. He was sentenced by Judge Louis H. Poliak to fifteen years imprisonment.2 Judge Poliak later granted Moskovits’s § 2255 motion to vacate the conviction on the ground that Moskovits’s trial counsel was ineffective, United States v. Moskovits, 844 F.Supp. 202 (E.D.Pa.1993), and granted Moskovits’s request to represent himself at the new trial. Moskovits was again convicted and sentenced by Judge Clarence C. Newcomer 3 to a prison term of twenty years, five years longer than the sentence imposed by Judge Poliak.
On appeal, Moskovits contends that his conviction must be set aside on either of two grounds: (1) that his right to testify in his own defense was abridged by the conditions imposed on the format of his testimony, and (2) that he did not knowingly and intelligently waive his Sixth Amendment right to counsel. Moskovits also contends that, even if the conviction is affirmed, the case must be remanded for resentencing because his sentence was based on impermissible considerations. We affirm the conviction but remand for resentencing.
I
Moskovits contends that his conviction must be set aside because the district court imposed unreasonable conditions on his right to testify in his own defense.4 He argues that these conditions were so onerous that he had no choice but to forgo his right to testify.
We express no view on the propriety of the conditions imposed by Judge Newcomer because Moskovits, by electing not to testify, failed to preserve this issue for appeal. Because Moskovits did not testify, any possible harm flowing from the conditions imposed by Judge Newcomer is speculative and cannot be evaluated in relation to the record as a whole.5 Accordingly, we decline to set Moskovits’s conviction aside on this ground. See Luce v. United States, 469 U.S. 38, 41-*130642, 105 S.Ct. 460, 463-64, 83 L.Ed.2d 443 (1984) (defendant must testify in order to raise and preserve the claim of improper impeachment with a prior conviction); United States v. Romano, 849 F.2d 812, 815-16 (3d Cir.1988) (when defendant refuses to testify, the harm flowing from an in limine order is merely speculative and, thus, not a basis for reversing a conviction); United States v. Nivica, 887 F.2d 1110, 1116-17 (1st Cir.1989), cert. denied, 494 U.S. 1005, 110 S.Ct. 1300, 108 L.Ed.2d 477 (1990) (defendant who does not testify may not challenge ruling regarding the scope of permissible cross-examination).
II
Moskovits also seeks a new trial on the ground that the colloquy with the district court at the time he waived his right to counsel was thoroughly “deficient.” In fact, as the government points out, Judge Poliak conducted a lengthy and detailed colloquy that was, in all respects but one, a model of thoroughness. Judge Poliak set out the dangers and difficulties of proceeding pro se, stating that it would be “an imprudent course” and that Moskovits would be doing himself “a very very grave disservice.” App. at 41. Judge Poliak spelled out the cumbersome procedures Moskovits would have to follow to maintain the distinction between his roles as lawyer and defendant.6 He endorsed the Assistant United States Attorney’s statement that Moskovits would lose the benefit of the advice of counsel regarding the most effective way to present his ease to the jury.7 Judge Poliak also appointed stand-by counsel. Nonetheless, it is undisputed that punishment was not discussed at the waiver hearing. In particular, Judge Poliak did not inform Moskovits of the range of punishments he faced on retrial.
For a waiver of the right to counsel to be “knowing[ ] and intelligent ],” which it must be in order to be valid, the defendant “should be made aware of the dangers and disadvantages of self-representation, so that the record will establish that ‘he knows what he is doing and his choice is made with eyes open.’ ” Faretta v. California, 422 U.S. 806, 835, 95 S.Ct. 2525, 2541, 45 L.Ed.2d 562 (1975). To ensure that a defendant “truly appreciates the ‘dangers and disadvantages of self-representation,’ ... ‘[a defendant’s] waiver must be made with an apprehension of the nature of the charges, the statutory offenses included within them, [and] the range of allowable punishments thereunder.’ ” United States v. Welty, 674 F.2d 185, 188 (3d Cir.1981) (quoting Faretta, 422 U.S. at 835, 95 S.Ct. at 2541, and von Moltke v. Gillies, 332 U.S. 708, 724, 68 S.Ct. 316, 323, 92 L.Ed. 309 (1948) (plurality)) (emphasis added); see also Singer v. Court of Common Pleas, 879 F.2d 1203, 1210 (3d Cir.1989) (no waiver where court faded to inform defendant of range of punishment he might be exposed to); McMahon v. Fulcomer, 821 F.2d 934, 945 (3d Cir.1987) (same); Piankhy v. Cuyler, 703 F.2d 728, 731 (3d Cir.1983) (same).
The government concedes that Moskovits was not advised during the waiver hearing that he faced the possibility of an increase in the fifteen-year sentence that had been originally imposed by Judge Poliak, but argues that his waiver of his right to counsel was knowing and intelligent because the record shows that he was aware of this possibility at the time of the waiver hearing. The *1307government frames its argument as follows: “[T]he record establishes that although not specifically advised of the possibility of an increased sentence at the waiver hearing before Judge Poliak, Moskovits understood that possibility before the trial commenced before Judge Newcomer.” Appellee’s Brief at 16. In making this argument, the government relies on the record of proceedings both before and after the waiver hearing conducted by Judge Poliak.
The government relies on United States v. McFadden, 630 F.2d 963 (3d Cir.1980), cert. denied, 450 U.S. 1043, 101 S.Ct. 1763, 68 L.Ed.2d 241 (1981), for the proposition that if the defendant has otherwise been made aware of the range of punishment he faced, the court is not required to notify him again at the time he waives his right to counsel. McFadden, however, is distinguishable on its facts in a material respect. In McFadden, the record was clear that the defendant was aware of the range of punishment he faced when he waived his right to counsel. As this court said, “[t]he nature of the charges and the range of punishment had been pointed out in MeFadden’s two initial appearances before a magistrate.” Id. at 972.
Here the record is not at all clear that Moskovits had been made aware when he waived his right to counsel before Judge Poliak that the original 15-year sentence would not serve as a ceiling on the sentence he could receive in the event he was convicted again. The government cites the PreSentence Investigation Reports (PIRs) that were prepared when Moskovits was originally sentenced and resentenced.8 In relying on these PIRs as evidence that Moskovits was aware that he faced the possibility of an increased sentence if found guilty a second time, the government assumes, implicitly, that Moskovits either read and understood the PIRs or that counsel then representing him explained to him that the maximum sentences set forth in the PIRs could be imposed in spite of the fact that Moskovits’s sentence would then exceed the 15-year sentence originally, imposed. The government cites no record support for either assumption, and we have found none. Thus there is no record support,.as there was in McFadden, for imputing to Moskovits knowledge at the time he waived his right to counsel that the original 15-year sentence would not act as a ceiling on his punishment. Accordingly, we see no basis for inferring that Moskovits was aware from the mere existence of the PIRs that he was facing the possibility of an increased sentence if found guilty a second time, particularly given our mandate to “indulge in every reasonable presumption against waiver” of the right to counsel. Brewer v. Williams, 430 U.S. 387, 404, 97 S.Ct. 1232, 1242, 51 L.Ed.2d 424 (1977).
The government also cites a conference in Judge Newcomer’s chambers six or seven days before the start of the retrial as evidence that Moskovits was aware at the waiver hearing before Judge Poliak five months earlier that he faced the possibility of a twenty-year sentence. The extract from the transcript of the in-chambers conference relied upon by the government reads as follows:
THE COURT: Okay. Now, my understanding of the law, and I mention this at the outset so that everybody knows my view of the law on this matter, and if you disagree with it that you will then have an opportunity to furnish me with the authority for your stance, is that this sentence having been vacated and a new trial being granted, we are in an entirely new ballgame. And this matter is like a new case coming before me for trial for sentence with the power vested in the presiding judge to determine, if appropriate, if there should be a conviction the sentence that would be applicable.
I understand this case preceded the guidelines, is that right?
THE GOVERNMENT: That is correct, your Honor.
THE COURT: And therefore this case will not be sentenced under the guidelines, is that correct?
THE GOVERNMENT: That would be—
THE COURT: If there should be a conviction. All right.
*1308Now, if anybody disagrees with that, please feel free to tell me but give me your authority for it because I’ve satisfied myself from independent research here in chambers that that’s the case.
MR. MOSKOVITS: Your Honor.
THE COURT: Yes, sir.
MR. MOSKOVITS: With all due respect. If I understand the law correctly, there’s two cases that come to mind. One of them is not—
THE COURT: If there are, you can do this in writing.
MR. MOSKOVITS: Oh, in writing?
THE COURT: Yes.
MR. MOSKOVITS: Thank you, sir.
THE COURT: I want — for a matter that important, I would much prefer to have you do it. It doesn’t have to be fancy and certainly not long, but I’d like specifically to have your authority so that I can, you know, search it out carefully.
MR. MOSKOVITS: Thank you, your Hon- or.
App. at 62-64.
While it is true that Judge Newcomer said he would have a free hand at sentencing because the retrial would be like a new case coming before him, he did not say anything about his authority to impose a sentence longer than fifteen years. Moreover, even if Moskovits’s response to Judge Newcomer indicates “that Moskovits himself recognized the possibility of an increased sentence and had conducted legal research in an attempt to determine the limits of the court’s authority,” as the government argues,9 Appellee’s Brief at 15, Moskovits’s waiver of his right to counsel would still be defective. For a waiver of counsel to be valid, the defendant must be aware of the dangers of self-representation at the time of the waiver. Welty, 674 F.2d at 188-89 (“to be valid [a defendant’s] waiver must be made with an apprehension of ... the range of allowable punishments”) (quoting von Moltke v. Gillies, 332 U.S. 708, 724, 68 S.Ct. 316, 323, 92 L.Ed. 309 (1948) (plurality)); McFadden, 630 F.2d at 979 n. 10 (Adams, J., dissenting) (“von Moltke makes clear [that] a defendant’s waiver of the right to counsel is made knowingly only if he apprehends the charges and possible punishments at the time the waiver is made.”).
On this point, the government’s reliance on McFadden, 630 F.2d at 963, is again misplaced. In McFadden, the record established that.the defendant was aware at the time of the waiver hearing of the range of punishments he faced because he had been given this information during earlier appearances before a magistrate. Here, in contrast, the government is asking us to impute knowledge to Moskovits at the waiver hearing before Judge Poliak on the basis of a proceeding that took place five months after the hearing. In other words, the government is asking us to extend McFadden beyond its holding and infer that a defendant had knowledge at a waiver hearing on the basis of proceedings that occurred five months later. This we decline to do, lest we fail to “indulge every reasonable presumption against waiver of fundamental constitutional rights.” Johnson v. Zerbst, 304 U.S. 458, *1309464, 58 S.Ct. 1019, 1022, 82 L.Ed. 1461 (1938).
The question we now consider is the appropriate remedy for the failure to inform Moskovits that he could receive a sentence longer than his originally imposed sentence of fifteen years. The Supreme Court has recognized that “[cjases involving Sixth Amendment deprivations are subject to the general rule that remedies should be tailored to the injury suffered from the constitutional violation and should not unnecessarily infringe on competing interests,” such as, “the necessity for preserving society’s interest in the administration of criminal justice ____ Our approach has thus been to identify and then neutralize the taint by tailoring relief appropriate in the circumstances to assure the defendant ... a fair trial.” United States v. Morrison, 449 U.S. 361, 364-65, 101 S.Ct. 665, 668, 66 L.Ed.2d 564 (1980).
Although the record does not tell us that Moskovits was aware at the time of his waiver hearing that he could be sentenced to a term longer than fifteen years if found guilty a second time, Moskovits certainly knew that he could again receive a fifteen-year sentence if found guilty at the retrial. Indeed, Moskovits admits that he knew at the time he waived his right to counsel that he could again be sentenced to a fifteen-year term. Appellant’s Brief at 6 (“the prior resentencing provided strong support for Mr. Moskovits’s understanding that the recently vacated sentence would have served as a ceiling at any re-sentencing following a re-conviction”). As Moskovits’s own attorney stressed at the waiver hearing, Moskovits was “ultra bright” and knowledgeable about the ease.10
Because Moskovits knew at his waiver hearing that he could be sentenced a second time to a fifteen-year term, the only prejudice he could conceivably suffer from the deprivation of his Sixth Amendment right is a sentence greater than fifteen years. Agcordingly, the appropriate remedy for the deprivation is to affirm the conviction but impose a fifteen-year ceiling on Moskovits’s sentence. Cf. Scott v. Illinois, 440 U.S. 367, 374, 99 S.Ct. 1158, 1162, 59 L.Ed.2d 383 (1979) (although the Sixth Amendment guarantees the right to counsel during a misdemeanor prosecution, failure to provide counsel is not unconstitutional as long as the defendant is not punished by imprisonment, even if imprisonment is authorized by statute); United States v. Reilley, 948 F.2d 648, 654 (10th Cir.1991) (striking down portion of sentence imposed on uncounseled misdemeanor defendant that involved conditionally suspended term of imprisonment but affirming portion of sentence involving a fine); United States v. White, 529 F.2d 1390, 1394 (8th Cir.1976) (upholding conviction but vacating suspended prison sentence imposed on misdemeanor defendant who did not waive right to counsel).
The twenty-year sentence imposed by Judge Newcomer is vacated and the case is remanded for resentencing.
Ill
We now turn to Moskovits’s claims of error at the sentencing phase of the retrial. Judge Newcomer gave a number of reasons for the twenty-year sentence he imposed, among which were the serious nature of the crimes, Moskovits’s prior involvement in the transportation and distribution of cocaine, Moskovits’s poor prospects for rehabilitation, and Moskovits’s lack of remorse and failure to accept responsibility for his crimes, as evidenced — among other things — by Moskovits’s refusal to accept the government’s plea offer. In addition, Judge Newcomer specifically cited his finding that Moskovits committed perjury at the evidentiary hearing on his § 2255 petition as a justification for imposing a sentence that was greater than the fifteen-year sentence originally imposed. Moskovits *1310argues that his case must be remanded for resentencing because Judge Newcomer (A) acted with actual vindictiveness when he imposed a harsher sentence after the retrial, (B) improperly punished Moskovits for refusing to plead guilty, and (C) erred when he found that Moskovits had committed perjury at the § 2255 hearing before Judge Poliak and considered this finding at' sentencing. We address each of these arguments in turn.
A
Moskovits does not attempt to invoke the presumption of vindictiveness that normally arises when a harsher sentence is imposed after a retrial. See North Carolina v. Pearce, 395 U.S. 711, 725-26, 89 S.Ct. 2072, 2080-81, 23 L.Ed.2d 656 (1969). Nor could he. We have held that a harsher sentence imposed after a retrial is not presumed to be vindictive if it is imposed by a “judge who ... ha[d] no material contact with the initial trial or sentence and ‘provides an on-the-record, wholly logical, non-vindictive reason for the harsher sentence.’ ” Rock v. Zimmerman, 959 F.2d 1237, 1257-58 (3d Cir. 1992) (en banc) (quoting Texas v. McCullough, 475 U.S. 134, 140, 106 S.Ct. 976, 980, 89 L.Ed.2d 104 (1986)). Judge Newcomer had no contact whatsoever with Moskovits’s initial trial and set out, on the record, plausible reasons for the harsher sentence he imposed.
Moskovits instead argues that the harsher sentence imposed by Judge Newcomer resulted from actual vindictiveness. The only proof of Judge Newcomer’s actual vindictiveness offered by Moskovits is Judge Newcomer’s statement that if he “were to sentence Moskovits to the same sentence that he originally received, it would countenance frivolous Section 2255 claims and encourage defendants to file them in hopes of gaining a reduced sentence long after their time to file Rule 35 motions had expired.” App. at 135. According to Moskovits, Judge Newcomer’s characterization of his successful § 2255 petition as “frivolous” reflects the actual vindictiveness with which he imposed sentence. We are, however, not persuaded that this statement alone is enough to establish actual vindictiveness, particularly in light of the numerous other, logical reasons Judge Newcomer stated for imposing the twenty-year sentence.11
B
After Judge Poliak granted Moskovits a new trial, the government offered a plea bargain involving a sentence no greater than time served. Moskovits’s rejection of this offer was a factor considered by Judge Newcomer when he imposed the twenty-year sentence. As Judge Newcomer explained, “[t]o me, [Moskovits’s] refusal to accept the plea is further evidence of his lack of remorse and failure to take responsibility for his crimes.” App. at 137.
We agree with Moskovits that Judge Newcomer erred when he considered as a sentencing factor Moskovits’s decision to exercise his constitutional right to a trial by jury rather than accept the government’s plea offer. United States v. Jackson, 390 U.S. 570, 581-82, 88 S.Ct. 1209, 1216-17, 20 L.Ed.2d 138 (1968) (invalidating death sentence under Federal Kidnapping Act because it could be imposed only, upon a defendant who elected a jury trial, whereas the maximum penalty that could be imposed on a defendant waiving this right was life imprisonment); Corbitt v. New Jersey, 439 U.S. 212, 223, 99 S.Ct. 492, 499, 58 L.Ed.2d 466 (1978) (upholding statute that allows judge to exercise leniency by choosing a lesser sentence for murder defendants who pleaded non vult); United States v. Paramo, 998 F.2d 1212, 1219 (3d Cir.1993) (prosecutor may not refrain from filing a motion necessary for a downward departure because the defendant elected to go to trial), cert. denied, — U.S. -, 114 S.Ct. 1076, 127 L.Ed.2d 393 (1994).
The government argues that Judge Newcomer’s comment, quoted above, does not show that he was penalizing Moskovits for having elected to go to trial but rather merely expresses Judge Newcomer’s view that Moskovits had been unwise to reject the plea *1311offer. The government also asserts, without explanation, that Judge Newcomer was not punishing Moskovits for exercising his right to go to trial, but was merely withholding leniency. These arguments are implausible, however, in light of the fact that Judge Newcomer made his comment in the context of setting out his reasons for the harsher sentence he was imposing.
C
Moskovits argues that Judge Newcomer also committed error in basing his twenty-year sentence on a finding of fact that Moskovits committed perjury at the evidentiary hearing held on his § 2255 petition. Judge Newcomer’s finding of perjury was based upon his reading of the transcript of Moskovits’s § 2255 testimony before Judge Poliak, considering the testimony of the government’s witnesses, and concluding that the version of the facts to which Moskovits testified was contradicted by the verdicts of the juries at his original trial and retrial. As Judge Newcomer put it, “[t]he proof that Moskovits perjured himself lies in the fact that two juries listened to the identical evidence [that Moskovits denied at the § 2255 hearing] and convicted him.” App. at 132.
Moskovits argues that Judge Newcomer’s finding of perjury was improper because it was not made independently of the juries’ verdicts. Moskovits relies on United States v. Dunnigan, 507 U.S. 87, 113 S.Ct. 1111, 122 L.Ed.2d 445 (1993), which holds that a district court that enhances a sentence because the defendant committed perjury must “review the evidence and make independent findings necessary to establish a willful impediment to or obstruction of justice.” Id. at 95, 113 S.Ct. at 1117 (interpreting federal sentencing guidelines). In other words, the sentencing judge must have a basis for his finding of perjury that is “independent” of the jury verdict.
In response, the government asserts that Judge Newcomer independently considered the testimony of the witnesses for the prosecution at the retrial, recognized that the juries by their verdicts had found these witnesses’ version of the facts to be true beyond a reasonable doubt, and concluded that Moskovits committed perjury when he testified at the § 2255 hearing to a contradictory version of the facts.
We are satisfied that Judge Newcomer did not err when he made a finding that Moskovits committed perjury at the § 2255 hearing. Judge Newcomer explained on the record that there were “numerous occasions on both direct and cross-examination [when] Moskovits testified that he did not take the specific criminal actions which the Government’s evidence established that he did take.” App. at 132. Judge Newcomer specifically cited Moskovits’s testimony that he did not receive phone calls from one of his alleged co-conspirators while he was in prison in Mexico, which was contradicted by the co-conspirator’s testimony and phone bills; his testimony that there was an innocent explanation for his actions in connection with a package of cocaine, which was contradicted by the testimony of five government witnesses; his denial that he directed two co-conspirators to travel to South America and purchase ¡cocaine there, which was contradicted by the co-conspirators’ testimony; his disavowal of ownership of a machine gun, which was contradicted by the testimony of four government witnesses; and his assertion that eight tape recordings of telephone conversations with a co-conspirator did not relate to drug transactions, which was contradicted by the testimony of the co-conspirator and two other government witnesses. App. at 132-34.
Although Judge Newcomer was not present at the hearing and thus not in a position to observe Moskovits’s testimony, Dunnigan leaves open the possibility of finding all the elements of perjury — falsity, materiality, and willfulness — when there are “numerous witnesses who contradicted [the defendant] regarding so many facts on which [he] could not have been mistaken.” Dunnigan, 507 U.S. at 95-96, 113 S.Ct. at 1117. See also United States v. Boggi, 74 F.3d 470, 478-79 (3d Cir.1996) (upholding sentencing judge’s finding of perjury under the Sentencing Guidelines, in part by reference to facts implicit in the jury’s verdict). Moreover, because Judge Newcomer was sentencing Moskovits under the pre-Sentencing Guidelines regime, he had broad discretion to consider any and all information about Mosko*1312vits’s relevant conduct and to determine what effect, if any, that information would have on the sentence. See United States v. Grayson, 438 U.S. 41, 51, 98 S.Ct. 2610, 2616, 57 L.Ed.2d 582 (1978) (upholding sentencing enhancement in pre-Guidelines case on sentencing judge’s view, based on government’s rebuttal evidence and cross-examination, that the defendant committed perjury during trial); United States v. Tucker, 404 U.S. 443, 446, 92 S.Ct. 589, 591, 30 L.Ed.2d 592 (1972) (in pre-Guidelines case, “before making [the sentencing] determination, a judge may appropriately conduct an inquiry broad in scope, largely unlimited either as to the kind of information he may consider, or the source from which it may come”).
The conviction is AFFIRMED. The twenty-year sentence imposed by Judge Newcomer is VACATED and the case is REMANDED for further proceedings consistent with this opinion.
. Because the offenses occurred prior to November 1, 1987, the United States Sentencing Guidelines do not apply. See U.S.S.G. Ch. 1, Pt. A(2).
. Judge Poliak granted Moskovits’s motion and disqualified himself from presiding at the retrial. Judge Poliak decided he should avoid any appearance of impropriety that might have arisen from his long association with the University of Pennsylvania, where Moskovits had been a student during much of the period covered by the indictment. United States v. Moskovits, 866 F.Supp. 178 (E.D.Pa.1994).
. The challenged conditions, set forth in the court's Order, dated September 21, 1994, were as follows:
The defendant shall, when acting as counsel, state the word "Question” prior to asking a question of himself as witness. When acting in the role of witness, the defendant shall state the word "Answer” prior to answering the question posed. Moreover, prior to responding to an objection posed by counsel for the government, the defendant shall note clearly that he is acting in his role as counsel, not as witness. Similarly, should defendant object to any question posed by counsel for the government on cross-examination, such objection shall be prefaced by a clear statement that the defendant is acting in the role of counsel, not witness. This procedure protects the rights of the defendant while minimizing the possibility of confusion.
App. at 76. In devising these procedures, Judge Newcomer relied on United States v. Nivica, 887 F.2d 1110, 1120-23 (1st Cir.1989), cert. denied, 494 U.S. 1005, 110 S.Ct. 1300, 108 L.Ed.2d 477 (1990).
. We are not persuaded by Moskovits’s argument that his testimony at the evidentiary hearing on his § 2255 petition makes the nature and impact of the testimony he would have given at the trial knowable. See United States v. Romano, 849 F.2d 812, 815-16 (3d Cir.1988) (holding nature of testimony defendant would have given at fourth retrial too speculative to be evaluated, even though defendant had testified at the first and second trials).
. Judge Poliak stated:
You appreciate that acting as your own lawyer, you would not be able to present those facts [of Moskovits's life] autobiographically to the jury except on such occasion as you would elect, if you elect, to take the witness stand as a witness. That is to say in speaking to the jury by way of argument, opening statement or closing argument, you would not be able to speak in the first person. You would not be able to say I. The presentation would have to be in terms of Mr. Moskovits. So the jury would continue to understand that you are there in your role as advocate, not as speaker about yourself.
App. at 49.
. The Assistant United States Attorney stated:
I understand his point that he is the person who knows what he contends to be his version of the facts, but in the normal processes of litigation, that gets communicated to defense counsel when the defendant and defense counsel then figure out the most effective way to present that to a jury and it seems to me that Mr. Moskovits should be made aware of the fact he's going to lose the benefit of that advice
THE COURT: Is there anything you would like to say with respect to [the Assistant United States Attorney's] very well-chosen comments, Mr. Moskovits?
App. at 52.
. Moskovits was originally sentenced to 17 years. Judge Poliak later determined that the mandatory minimum sentence should not have been enhanced and resentenced Moskovits to 15 years. United States v. Moskovits, 784 F.Supp. 183 (E.D.Pa.1991).
. In a variation of the government's argument, the dissent asserts that we can know with certainty that Moskovits would have chosen self-representation even if the waiver hearing had been flawless because he chose to represent himself even after "learning what he had at stake” during the in-chambers exchange. Therefore, the dissent argues, the defective waiver hearing "did not in any way affect the subsequent course of events” and the judgment should not be disturbed because it is not causally connected to the constitutional error. Because an unknowing and unintelligent waiver of counsel is a constitutional violation that pervades the entire proceeding, it can never be considered harmless. United States v. Welty, 674 F.2d 185, 194 n. 6 (3d Cir.1982) (noting that the right to assistance of counsel is "among those 'constitutional rights [which are] so basic to a fair trial that their infraction can never be treated as harmless error'") (quoting Chapman v. California, 386 U.S. 18, 23 & n. 8, 87 S.Ct. 824, 828 & n. 8, 17 L.Ed.2d 705 (1967)); see also United States v. Salemo, 61 F.3d 214, 221-22 (3d Cir.1995) (refusing to apply harmless error analysis to deprivation of right to counsel at sentencing). In any case, we can only speculate about Moskovits's reasons for proceeding to trial as his own lawyer after the in-chambers conference. We can only speculate about how long it would have taken standby counsel to get up to speed to try Moskovits's case, and whether any continuances that might have been necessary would have prejudiced the defense because of the potential loss of witnesses then available to testify-
. Moskovits’s attorney stated:
The only thing I would say, Judge, is that he knows the case well. I think you've had enough experience with him to know that he is ultra bright and ultra articulate.... He is not someone who is unfamiliar with the case. He's lived with it and I must say, Judge, a lot of the research that went into a lot of the material before you over — I've been in this case, what, four or five years now — has come from [Moskovits]____
