Caps already had been replaced (except for the color units) before I get the set. I have changed c114 to 0.1. Horizontal drive voltage is -20v on pin 5 on the 6CB5 (with 105 volts ac). The +385 v supply has only 317 volts (with 105 ac) and 365 volts with 114 volts ac. I measured crt heating voltage again, but now directly on pin 1 and 14 of the crt, it is 6.15v (with 114 ac). But I checked the focus control R129 and opened it. It had burned out inside, see photo. The focus control seems to be the true source of inconstant picture and arcings! I have renewed it. The picture now is sharp and clear with rich contrast and brightness. But there is still something to do to set the d.c. currents properly. Perhaps the 5U4 are weak because of the additional electrolytics for the canadian 25 cycle rectifying.
