Zenith 12B14C52 Sparky Damper tube
TV works great for a few minutes then the damper tube plate gets red and sparks fly in horizontal output tube 6LB6, of which I have lost 2. Hoping it is not a flyback issue, I will start replacing the disc capacitors in the damper circuit. Shorting capacitors on the boost line are suspect as well. I have R.L Goodman's Zenith service manual volume 2. If you have any ideas, please reply.
