First of all, does anyone have an electronic copy of the a212 schematic?
Secondly, does anyone know the proper load impedance for the a212's speaker output? It isn't printed anywhere on the chassis of the amp, and I'm not sure I trust the shoddy looking speaker wiring that came with it. It appears to be wired as a 4 ohm load and seems to work, but I want to be certain.
Thirdly, has anyone biased an a212 and lived to speak of it? Or does anyone know of resources on power tube biasing that would be helpful?
