Old TVs are better!

Well, there still is a lot of work to do. I still have the width problem when brightness and contrast is increased, and my 25 watt 5.1ohm resistor that I am using in the B+ to drop the excess voltage, (since I used silicon rectifiers to replace the selenium's), gets so hot that it actually smells a bit. I may have to go to 2 separate resistors as I am afraid that the excess heat will cause it to open up. Then there is taking out the glass and cleaning up the cabinet, pencil box, and making it look "new" again. However I still want it to look original as possible. Hope I can get the cabinet looking nice, but had to get the set operating first. I may order a new damper, HV regulator, another horizontal output tube, and horiz oscillator tubes to see if that takes care of the width/ focus problem at higher brightness. Of course once I get the chassis mounted back into the cabinet, then I will try to set the purity and convergence as close as possible. There is a metal plate that the chassis sits on top of, and I hope to maybe mount it underneath somehow so if I need to work on the circuits from the underside that I don't have to pull the entire chassis. Any old retro TVs are an on going project, always hoping to improve upon it.
