Hi Loudthud,

Many thanks for your reply. I'm located in the UK but I haven't worked out how to show my location yet as I'm new to all this.

There seems to be distinct lack of information on the internet about some electronic products - particularly vintage amplifiers (1970's to 1980's). Why do some manufacturers behave in this way, after all a disclosing information about a 40 odd year old amplifier is hardly going to lose them any business!

Anyway, the project is going well and after some repairs to broken/corroded tracks on the pre-amp board and replacement of some of the pots, I now have a working amp.

Many thanks,

Tony.

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.
