Dear Autospec:
You should send your el34 amplifier to Sophia Electric's service centers for services. The Sophia Electric's services for amplifiers are reasonable and the turn around are quite fast.
You cry for no schematics, but at this time, did you see Goldmund or any other major high end amplifier makers to share circuit diagram to users?
Simply, the flood of copycats from Far East is a problem. Sophia electric, being an US design and manafacturing company, is no different from Goldmund and others to protect its own design. Posting Sophia Electric design over internet may get you in legal trouble, if you are not careful with fact that U.S. government is taking intellectual property seriously.
Audospec, you may have a Chinese copycat of the Sophia amplifier, otherwise, you should have sent your amplifier to Sophia Electric already.
