progress...
the color demodulators seem to be working, I have a loose focus lead (not sure if I knocked it out or if it was already loose, I had very poor focus until I pushed it back into the socket. The CRT socket is pretty loose on the tube so I have to be careful (it was loose when I got it). sound is good, sync is good. have to work the vert scan, prob a cap (there is a paper cap in there).
HV seemed a little low, about 21-22kv full on. Will have to look into that, maybe a low B+ maybe shunt tube (I checked the HOT current, about 220, but did not check th shunt 6BK4). the HV adj does work, just lacks head room. It looks completly orig, I see no evidence of any work being done.
I think I will try a new vert tube, and check that electro cap. then need to find the B+ and check it. This set uses a doubler so I guess if one or both of the of the doubler caps was a little weak the B+ could be down.
