No problem, glad you checked in, thanks for your thoughts.
It was one of the used-tested 6П14П tubes that was red plating. This was before I learned that the 6П14П has lower ratings than the 6П14П-EB. It now has a new set of 6П14П-EB tubes. I ran it for around 20 minutes or so earlier during (and after) adjusting the IBAM trimpots, and I never saw any hint of red in any of the 6П14П-EB tubes.
So...did you ever find a power tranny for your Fisher 500-C?
As for this TA-600: I've installed the inrush current limiter and it is playing right now through a bucking transformer (107.4 volts instead of 125). In a few minutes, I'm going to shut it off and button it up (reinstall bottom cover, front panel, and reinstall in case). Having re-cleaned the Selector and Mono-Stereo switches, the left channel is now coming up along with the right as the tubes warm up. No more snap, crackle, or pop.
