How critical are these cap values (RCA T-100)?
 

There are two paper caps left in my RCA T-100, C164 (.018) and C165 (.039), both rated 1000V.

Not having those exact values, the best I can do with parts on hand is to wire two 600V caps in series: .047 + .047 = .0235 for the .018, and .1 + .1 = .05 for the .039.

OK? Or should I cool my jets and wait for exact parts to arrive in the mail?

The HV supply is making 8KV, not 9KV as specified.

C165 looks critical as it is in the flyback/damper circuit. It may affect width. C164 looks like decoupling. I have to say that is a bizarre high voltage stage. They return the doorknob capacitor to the damper plate. I usually see them to ground. The more I think about it, C165 may affect high voltage. Keep us posted!

OK, I won't fudge, then. I needed some other stuff from Mouser, anyway.

After the new caps arrive, I need to thoroughly check out the horiz & h-v circuits. The 6BG6 output tube makes a nice blue dancing light show inside, something I haven't noticed in my CTC-11s. The width and horiz linearity adjustments are unresponsive, too. Perhaps not surprising if these caps are defective.
