My new Zenith 20YIC50

[TUD1]

Got this set this weekend along with the CTC-15, but just now got around to putting it back together. The picture tube is marginal, but it will make a decent picture. The high voltage however, is out of control. When I measured it, it was at 41 KV! I tried adjusting it, but the stupid control would not move. It's the kind that you have to stick a pencil eraser or something in to adjust. I don't like it a bit. I'm just going to keep the brightness cranked, so hopefully it will keep the HV down around 30 KV, and it won't destroy the tube. I think this set uses those darn varistors, so that's probably what's wrong with it.
