1970s Zenith Console - Troubleshooting

[ThePlague]

Thank you all for your generous help! Certainly would not have gotten to this point without it.

I will make a list of items to work on a knock them off the list when I can. I think cleaning the contacts on the duramodules will also go a long way.

There is definitely some carbon tracks on the socket (I believe visible in one of my early photos of the set) so that will get the cleaning treatment and possibly a replacement if its too bad.

I found the source of the snap. Its my fault. There voltage divider kit I used had too short of cable for the focus and ground wires. I spliced it with the wires from the old divider (solder) then filled around the solder with silicon and heatshrinked it. Apparently it wasn't thick enough and its arcing from the solder joint to ground (about a millimeter arc). Is there a more suitable way to lengthen high voltage cables besides finding the right kit?
