Hi,

My Audiolab 8000P went faulty on one channel, I tracked the fault to
the 2SC2911 pre driver and replaced it and its compliment in both
channels and all is ok.
But my question is, what's the trimmer pot for? does anyone know
where I test and what's the parameter?

Thanks in advance
Craig




When I was a lad and used to work there (1983), IIRC it was to set the
bias current but I'm bu**ered if I can remember what it was now.

Why did you do both channels for, were they both U/S?...

Not to start with but I took the transistor from the other channel to
compare them and it was duff by the time I'd got it out and I wasn't heavy
handed with it.
I decided to change the compliments too while I was at it and neither of
them survived desoldering so they were obviously all on their last legs.

Ah perhaps a bell to tag mclaren and ask to speak nicely to their
service dept!.....
