Default Accuphase M-60 Service Manual wanted

Hello,

any idea where I can get one in good quality?

I know the available 2-page schematic in pdf, but it is not of good quality and hard to read.

Thanks,
Gerhard

At least he's halfway there.

Not a full SM, just a schematic, and not the best copy ever seen. But it's all i have.
Accuphase M-60

Best regards

Edit: My bad, didn't read properly the whole text

You're right. I just checked, and though the link says 596Kb, i just get about 192Kb. Strange

I tried another site: Speedshare
Hope this works.

Edit: Yep, it did

Jan Dupont, thank you very much.

Here is a working link for the ugly 2-page-file:

http://www.dephison.com/accuphase/m60.pdf


Maybe someone can help me in adjusting offset and bias.
Where are the potentiometers (in the schematic) and where and how do I connenct the meter? Any precautions?

I have got a pair M-60s recently. One is getting warm and one stays pretty cool after playing a while. So I think I should look after the adjustments.

Cheers,
Gerhard

VR2 bias adjust (quiescent current) IMHO
VR1 offset adjust.
Bias is usually measured across an output emittor resitor, here 1-Ohm 10Watt.
Offset just at the speaker output terminals.
