Hello,
I have here one of the New generation Sound Burger clones. It is the Crosley Portable turntable called "Revolution" model CR-6002. The problem is that the motor is running too fast! How would it be possible to regulate it to the right speeds to 33 1/3 and 45 rpm? I unmounted the unit, but could not find where to adjust that. The spindle motor is there, with 2 small belts, meaning there is an intermediate spindle between the motor spindle and the platter spindle. I checked the belts and everything seems all right. Any help to solve this problem? It's quite annoying, because the speed increase can sometimes be felt while listening. A song lasting 3:16 on at normal speed on a stroboscopic turntable barely lasts 3:10 on this one. Thanks in advance. Luc |

If I was making recordings with this POS, I'd fix the speed problem in the digital domain after doing the transcription. The better audio editing software has facilities for doing this. Otherwise, speed adjustment is either going to involve fooling with the motor speed control or actually turning down one of the belt pulleys. |
