Yeah, how bout them Giants!!! We stayed away from the dumba**** in the streets and had a good celebration of the long season. Won't happen again for awhile unless they strike magic with some signings.
Looked at the amp this morning before work. Swapped tubes to test for a failing tube. The blue glow is from the glass, the red is the plate, definitely the plate glowing. Tube filaments come on, then the blue starts and flickers, then the plate starts to glow.
Shut the amp down and flipped it over for a quick visual. I f'd something up royally. There's heat damage visible on the power supply chokes (can't even read the C-7x on the paper anymore, it's all brown) and on the plate chokes (can't see Mike's writing, looks like varnish has run and looking down at the bobbin (?), it's not light yellow anymore, I can see brown thru it). I'm surprised I didn't smell anything before.
No other visible damage, fuse never blew, resistors, outputs and grid chokes all look fine.
Looks like it was overcurrent on both channels and one tube finally gave me indication. I'll email Mike to see how much of a beating the BH-6's can take and put in a order for new if needed.
Tubes are really forgiving, this amp was playing music for at least an hour before I noticed the problem.
Here's my plan, please let me know if I'm on the right track:
1) remove damaged parts, replace (resistor in place of the power supply choke, and a Hammond choke for the BH-6 just for testing)
2) inspect, reheat grid choke connections, grid resistor
3) check 2A3 socket pins (noticed the tubes weren't in flush to the socket when I removed them)
4) check power supply wiring, used a 302ax power supply transformer for the first time, to make sure I wired it in correctly
5) do a round of voltage checks
6) Come back for help!!
