Hi there,
Firstly I do apologise if this is in the wrong place, or even if it should not be here at all. If so I am sure that someone will berate me, but I could see nowhere else!
I have had the 690c passed on to me - not working of course. It has a PSU problem. On the only PCB (C6409-A-54) There is a surface mount transistor Q3. Unfortunately it has become upset beyond recognition. Service info seems to be unavailable, but someone somewhere must have it. Can that someone tell me what the transistor is please?
Even better - a circuit of this part of the board might save me a lot of tracing.
Thank you for at least considering this.
Tony...
