hi shannon
the info you gave me fix the problem.
the instructions for the first bias setting does not match info.
the 12ax7 tube does not glow very much. hard to tell if it is on.
i have all my settings. everything seem ok. after burn in will hook up spk.
the anolog meter works nice. switch between l/r tube the same.
i will get my son to take some photos.
thanks again.

Thanks for the feedback, AudioRay - I'll take a look at it.

Can't wait to see your pix. Candy apple red with pinstripes?
