awe-sum,
Pioneer SA-810 uses the 6AN8 pentode as a common cathode amplifier and the triode section as a split load "concertina" phase splitter. Unfortunately it is not really suitable for this circuit.

I do have a a high resolution scan of the SA-810 schematic. It is 1.8M file size so I can't post it. Send me a PM if you want it.

Cheers,
Ian

Really, Ian?
Oh man, you made my day! BUT:

"Sorry but you cannot currently send emails to other members because your account is under moderation. If you are a new user, you will gain full member status after you have made a few posts."

So will you pls mail the scan (bmp by any chance??) to verne1a@gmail.com - the bigger, the better, cause i use to print out parts of the schematic for work sheets (as i introduced myself: pretty old school i'm afraid).

thanx again
Verne
