Hello,
I have the above amp and owners manual, which includes a schematic but no mention of what the bias should be set to, or I am so stupid I missed it. Is there a seperate "service manual" that I can aquire?

I only saw the bias adjustments on the schematic, is there a way to adjust DC ofset short of replacing input devices?

Has anyone experimented with tweaking this amp for "home" use, like increasing supply capacitance, replacing rectifiers with freds or schotky devices, or other such audio nervosa?

It is an enjoyable amp as is, but when I put my P-P 6550 amp back in the chain, it is so much more transparent it is ridiculous! Do I just need to enjoy it for what it is and shutup?

Thanks in advance,

Russellc
