RE: GM20 questions

Hi Chris,
the resistors are in fact 51R on either side of the 50K trimmer (I have replaced the bloody awkward to access single turn board mounted trimmer with a 10 turn Vishay Cermet, side of chassis mounted for easy adjustment whilst in use !)The component labelled MV1 is an 82v MOV.
Hope this helps you somewhat....;-)
