It may also be that fold down monstrosity with ITR's, we all hated them.
On latter sets vert was common problem. Always two 220K ohms &
a transistor.

I'm looking at the schematic right now, and it's the weirdest damn thing I have ever saw, very modular, SCR on main power, HUGE electrolytic capacitor on input line to main rectifier (800 mfd )
most power seems to be driven from FBT.
Only 2 electrolytic caps on the vertical module, but I do think I see 2 220K res you mentioned, if i ever DO decide to work on this damn thing, I'd have to go over the entire vert pcb to find why it was losing height / linearity.
This seems to be one of the most poorly built sets ever out of RCA
Ref..
From 1970 on a few years Zenith offered some hybrid 25V sets. Some Avanti cabinet sets even have that chassis.
I remember seeing a Hybrid 23DC14 type (4 tube ) long ago, but not seen any in quite a while.
