Sunn A212 Schematic

[Dinsdale]

I can't seem to find a schematic for this model online.  Has anyone come across one?

Should I need service here in Seattle, I doubt anyone would have one.  

How often should the bias be checked and adjusted?

Thanks!

Fender has the schematic available for this amp.. though the copy youre likely to get is somewhere in the realm of a 145th generation. =P
I own this amp as well and after a little tweaking here and there it is the best sounding amp ive ever used. id like to find another.  though no one seems to have ever heard of this model.
ive repaired just about everything in the amp.. so if you have any questions let me know. i'll do my best to help.
