Schematic is diagram 7, scroll down a bit: Amplifier Audio Innovations Series 500
I suspect above is the most reliable source for the original schematic.
These amps had a few under-spec parts which have been appropriately upgraded. I have one of these amps amps converted from integrated to straight power amp.
To double the power, please comment on my proposal to buy a 2nd amp and convert both to mono. Besides doubling power does quality likely degrade?
Does mono conversion require more than internal wiring change?
Each transformer has 4/8/16 ohm taps. What are the tap assignments in mono (impedance wise and physical identification?)
Thank you for your consideration.

Probably not a good idea for most tube amplifiers, and the 3dB increase of power is minimal.
The sound quality would degrade, regardless.
