the 23x chassis is driving me nuts. There just is not much too the HV reg circuit, If I add two more VDR's in p with the orig one I can get the 6HS5 to clamp down on the HV enough to get it to 25kv with the brightness and screens all the way down. But I still have some other issues, Seems like the edge pin cushioning is not working on the top half fo the screen, if I turn the color down i can fine tune and get a good B&W but if I turn up the color I get real bad chroma crawl. Fine tuning is super critical. If I turn in some old vintage programming like that on RTV, I get a very decent pic, turn on the super bowl and its a mess. I think I am going to bag this one for a while. I still dont understand why the HV reg is such a problem. I did try another 6HS5 from another set that is working fine. Beside the VDR there just is not much in the circuit to go wrong (a few resistors that check ok, and a .047 cap that I dont think will be a problem, but I did not check it). Boost voltage seemed fine (it goes to the VDR, which then goes thru a few resistors and a pot to the grid of the 6HE5 tube).
