Hi Graham,
I have decided to ask you a question as you seem to know what your on about in these forums. Not saying others don't.

I have a Studiomaster P7, [actually i have 2]. I am a sound engineer by trade, not an electrician/electrical technician, so fixing more than obvious dry joints on boards is all i am able to fault find really.
I have one channel down, no signal looks like its coming though at all, nothing down any auxs, etc...

Now here's my question...fixing it... If i can locate a schematics I could take it to a tech and pay him to fault find and fix. However Studiomaster, and their archive dept do not carry such documentation. Any chance you have a schematics for one, or can hep in any way...?

I hope this is not out of order to ask you such a simple question, as i have read some of your posts, and you are speaking in languages that quite frankly go over my head. lol But any chance you can recommend a good course of action?

I live in Hull, yorkshire, UK btw

I could send a working module and a non working module out the desks, although i don't know if this is how a tech would fix it, or whether they would need the full desk?

Many thanks Martin, acousticjam@hotmail.co.uk

It's usually a blown transistor or a blown op amp. A tech with test equipment could fix it. Yes it could be fixed without the desk, just a power supply can run it for troubleshooting.
I would fix it for you, but I am in California. I'm sure there's a tech closer to Hull. Any tech who repairs amplifiers in a music shop should be able to fix it.

Thanks soundguruman. Yeh i was thinking its probably the op amp. I really was after locating a schematics for it. But thanks for the advice. I am thinking of taking a spare op amp out a group channel i dont use and sticking it in each of the op amps on board, seeing if that brings it to life.
