I have recently decided to refurbish my Studiomaster P7 and also use opportunity to service and calibrate.
I noticed the LED db meters were uneven at times, despite both faders on max, one channel would peak lower than other etc.
Also one channel on bus doesn't seem to turn.off during slate test, no matter if fader on or off or twitching.
So anyway I have everything disassembled and my multimeter ready but im appalled at the lack of info out there.
Going to make a YouTube video when I figure this out, however is there a knowledgeable person who can help?
Can do by text, forums or live even.
I just want to know how i can find out what the channels are calibrated to a d where exactly are the faults occurring. Which part of the channel strip should I be poking with my volt meter?

last year i spent 3 weeks cleaning every channel on an old Studiomaster only to find after all that it had some faults i could not diagnose and paying someone else to fix it was really expensive.. it might be more cost effective just to buy something s/h that works... that's what I did.
BUT if you clean it thoroughly it might be 100% after that, sometines they are.... all i can say is LABEL EVERYTHING YOU REMOVE before cleaning!!! - Label every channel & particularly every bus channel, because the busses have jumpers and if you put them back in the wrong order when you re-assemble then everything will be wrong.
then after cleaning it properly and putting it back together, if some pot or fader crackles or makes some noise then replace it would be easiest i think.
sorry I cant offer more than that - my one regret in life is that i never learned circuit electronics.
I had an idea for a script once. It's basically Jaws except when the guys in the boat are going after Jaws, they look around and there's an even bigger Jaws. The guys have to team up with Jaws to get Bigger Jaws.... I call it... Big Jaws!!!
