Pink Triangle Turntable Repairs

Pink Triangle

This was in need of some tlc, the motor supply used a DIN plug which had been connected to an Audio Vois power amplifier!

  1. 1) The power amp provides two 30V supplies at the DIN socket
  2. 2) The turntable needs around 9V to power the motor

This may have been a disaster in the making, however it turned out not too bad. The rectifiers had all but melted in the power amp and the plug had been wired to short the two, 30V supplies out, good for the turntable (saved the circuit from damage) not so for the power amp which needed the rather melted rectifiers replacing.

The chassis of pinky needed repairs where the motor fastened and the speed switch soaking in WD40, connecting a supply to the turntable got the motor working but any change in the voltage would alter the speed dramatically and it would have to be reset with the presets. I used a 9V regulated PSU which didn't allow the 45rpm speed to be set but we weren't bothered about singles.
