The 6DQ6 is making good ground contact on pin 8. I wrapped a thin wire around that pin and reinserted the tube. My ohmmeter shows it's connecting to ground. I grounded that little wire to the chassis and briefly powered up the set, and got the same old symptom.
I borrowed another 6DQ6 from my Philco Miss America and briefly tried it out. Same symptom: no HV.
Before attacking the couplate, I'll take out the chassis and re-clean the holes in the 6DQ6 and 6CG7 sockets and verify that they are connecting to the right spots.
If I do rebuild the couplate, what about voltage rating for those little caps? I have 500V dipped mica caps in the right values. I have some 1KV and 2KV rated caps, but they are ceramic and much larger.
I'm tempted to try replacing the couplate from above, since every time you pull and reinstall that board, you increase the chance of creating new problems.
