Thanks Dave, I need to locate a schematic that hopefully includes transformer winding resistance values for the flyback, and I need the bias voltage along with other voltages. I am really spooked that perhaps I have damaged the TV. Somewhere I have read that you should remove the HO tube when slow starting an old set with a variac or for me the 100W light trick. Not as effective, but better than nothing. So, I ran the set for several hours at the reduced voltage and no tube. You mentioned that no tube causes damage and I know that other high current issues cause damage so I am guessing that the damage would mainly be to the flyback.
It is when I added the tube that problems became evident. The first time I powered it up the tube was glowing red (obviously something causing a high current draw) and there was smoke that smelled like a resistor. So the was not really operated at full potential with NO HO tube. And when it smoked I did not operate it for more than a few seconds. Now I did take the cap off of the HOT and let the set work a while because there is no smoke or red hot tube with the cap off. Hopefully I did no permanent damage to more than maybe the HO tube itself.
