Luxman a-312 manual ?

opa · 8th May 2006, 01:02 PM

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.

See? Told you it should be easy.

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