What could Account for This? RCA 9TC-240 Power Issue

[Chris K]

I saw on his YT channel Bob had a series on a similar chassis. I replaced the power resistors, the electrolytic caps (more on this later!), the tubes in the HV box with known good ones and most of the paper caps. The voltages coming out of the bleeder network are pretty close to what they should be. I actually brought this TV up on original components when I started restoring it and I got a small, dim raster on the 10BP4.

But the TV is only drawing 1.5 amps when it should be drawing about 2.2 A. The high voltage is low at around 5Kv. I do not have any light on the screen of either the 10BP4 (tested OK) or on the technician 5" CRT. The brightness control ohms out close to perfect.

Any suggestions on where I should start looking to run this down? I cleaned the tube sockets in the HV section and checked the pin tabs for good connections and possible shorts but found all OK.

On the electrolytic caps, check out my other thread about the Adapt-A-Cap issue.

TIA all
