I am sure someone will pipe in with the proper replacements. They have to handle the 1 KV spikes on the hoz output plus the 130 VDC.

Reason this is important is the HV runs at 30 KV. Every cap that opens
adds apx 2KV. If all 5 open you are over 40KV HV. I had one where 4 were open & that set sent lightning bolts from from the HV. It will work with a few bad but it will slowly eat up the HV tripler, CRT socket, HV divider when used & Hoz out. The ozone is a sure symptom of trouble.
BTW you may hear about the 4 lead cap. Its the same idea but only on newer chassii.

I managed to pick up 4 NOS Zenith 22-5001 caps on Epay. It looks like that is the last of them. I grabbed a 22-5001 Zenith equivalent by Associates. I figure this will be better than what is current in the system.

As much as I'd enjoy having a Tesla coil, inside of a TV is not where I would want it. Based on the scorch marks I am seeing on the socket and elsewhere, it would seem that your analysis is correct. I'll report back once I get these new caps swapped in.

Thanks again for your help!
