Don,
Thanks. Thats where the filament voltage comes from. What was wrong was the sweep PCB was cracked. I think it was cracked when I got it. The top part of the PCB had two traces that were disconnected because of the crack. I scraped off the solder mask, soldered the broken trace and the set seems to work fine, with sound and picture. With no signal I get snow on the CRT, so I think thats a good sign. I'll test it with a signal and see how the picture is.
Hawkwind,
I was looking for that article. Thank you.
