The 270 was DC.....measured with my meter on the hold coil.
Now, here's something interesting. DavGoodlin was kind enough to show me how to get the sawtooth on my scope, got nothing. But it was also the first time I'd tested it under full line voltage....I'd been running it on a variac at about 85V. Just me being cautious.
Since I got nothing, I went back to test the voltage at the same point on the horizontal hold coil with the set plugged in at full line voltage. It started out at about 280 VDC, and over the course of 30 seconds dropped off and ended up leveling off at 65 VDC.
. No AC voltage shown.
I didn't have time before work this morning to re-check pin 6 of the 6CG7, but I will later.
