Does the absence of a preliminary examination by the judge result in a reversal?

Nevertheless, failure to follow this procedure does not require reversal. The indicated procedure is intended to avoid a mistrial or reversal resulting from an inaudible and prejudicial tape being played to the jury or an inaccurate transcript being submitted to them. Cf. United States v. Tortorello, 480 F.2d 764, 785, n. 18 (2 Cir. 1973). The absence of a preliminary examination by the judge is not in itself ground for reversal. We turn to a consideration of whether the tape and transcript in the instant case were inadmissible and prejudicial.
