Good afternoon all,

I'm new to this forum so if I make any mistakes, please forgive me.

I'm restoring (or trying to) a McGregor V4S PA amp. So far-so good. I have managed to solve a couple of problems but I have been thwarted by a lack of information on these amplifiers.
I contacted McGregor UK who said that it is not their policy to give out or sell service info (or indeed a circuit diagram). Does anybody out there have a schematic for this amp please.

Many thanks,

Tony.
