Hello everyone,

I need to trade e-mails and probably speak with someone who can determine how to set the bias pots (and possibly L/R balance pots?) on one of those Audioromy FU-29 amps (they are 829B tubes) which are showing up on eBay.

Here is a photo of the inside - volume pot is at the top left of photo. I know how to use a digital VOM, but you'll have to guide me through the rest step by step.

I can send the pin-out information for the 829B tube. The system here is giving me grief about sending a pdf file.

The manual is in Chinese, and I can send scans, but from just guessing it wouldn't be of any help even if it were translated. Appears to be more of a spec sheet than anything truly informative.

Thanks,
Mark
