Chad (or anyone);
I never smelled anything burning or smoking on the set. But it seems when I put the last two tubes in (which included the 12HG7), it got pretty bright, like a new set. I also adjusted the back of chassis to maximize brightness, sharpness and picture quality. After that, it seems things started to go downhill.
However, I don't think the HO transformer was burnt out because for two days there before it died I was able to get it working again by either positioning the 12HG7 tube just right, or lifting up one side of the set and setting it back down "hard."
Is it possible that all of the adjusting I did and all the new tubes overloaded something?
Note the 6CL3, aka, "6CJ3/6DW4B/6CH3" died on me in the process. Will be checking eBay today.
PS. I still have not pulled the chassis. Working through the bottom of the set (cut away all the particle board that had air wents and removed) with the set face down.
Thanks again for your help and advice,
Carl
