You might try Min at Tube Audio Lab, he's done good by me.
GM70 SET?
There are lots of schematics around the Web for GM70 SET amps. I think, given my speakers (KCS Fostex F200A; reasonably but not highly efficient) that GM70 SET would work very nicely in my room.
Does anyone know of an independent amp builder who'd be a good choice to build a custom pair of GM70 monoblocks? I know about SAC Thailand, but I'd prefer to deal with someone in the US.
