Default Luxman a-312 manual ?

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.

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.
