Hello Everybody,
I recuperate an old Luxman A-312 amplifier which is broken down and i am desperatly searching the service manual. After a lot of search, even to specialised service manuals sellers, nobody have this document.
So, if you get it, it would be VERY kind to make me a copy.
Thanks a lot.

Hi opa,
Sorry, I looked around and didn't find it. Someone out there may have some information.
It still should not be that hard to repair without a diagram. You could start by letting us know what tests you have done. Pictures of the amp board, top and bottom may help too.

Thanks a lot Chris for your proposition.
But my Luxman is repaired, i just need the service manual for adjusting many things like quiescent current, or changing some capacitors and AOP.

Hi opa,
Bias on Luxman is on the high side (30~60 mA) The heatsinks should get no hotter than warm to the touch.

See? Told you it should be easy. 😉
