Well I must have made an error at some point. I was replacing the resistor chains in the high voltage area, along with the shorted ac cap and a few resistors on the pots. Now when I turn the set on and the flyback area kicks in something makes a horrible squeal. I was getting an image, and adjusting the horizontal sync control would change the noise, but I was not getting any image or sound like I did before. After turning the set on and off a few times I no longer get high voltage. I ohmed out the flyback and it doesn't appear that any of the sections are open, I'll have to check for shorts between the windings. My hope is that the problem is due to my replacing the resistors in the high voltage chain but not putting any insulating coating on them like was there before. I ordered up a can of corona dope and will see if that changes things when it arrives wednesday. The fact that adjusting the sync did effect the sound really makes me think there is some issue around the 6l6 and 1B3 tubes, though I don't know why this would also kill any sound or video.
