Well, it is definite. NO HV.

I spent some time going over the chassis looking for signs of anything that had gotten hot. The 3 E-Cap cans were running cool. I checked the flyback to see if there was anything going on in there (signs it had gotten too hot, etc) and it looked good. As a matter of fact, this chassis has virtually had zero time on it. There is no dust/dirt, I mean none in the hv section or around the yoke. Just a light dust layer from sitting.

I did hear a little sizzle and smell a hot component in the hv area. Perhaps there is a bad cap on the underside of the chassis. I will have to pull it and have a look. There is an odd component just below the focus control that was a bit loose. It is a circular shaped component with two wires going into it. I disassembled the component and it seems to be a coil of some sort.
The windings wrap around a plastic piece and are covered by a cloth tape and this is sitting in a clamshell, ferrite core that appears to be more of a choke than anything but does get a little warm. A ceramic resistor at the flyback tuning coil does get customarily warm/hot so there is some power in there somewhere.

I know there were paper/wax caps in the hv section of my CTC-21 and CTC-38 chassis. Did RCA put those there in this chassis too? It would seem kind of odd since it is just chock full of orange drop type caps.

Tube chassis are so much easier to deal with. This is my only vintage solid state set and I think I will keep it that way.

Any thoughts as to the HV problem would be appreciated. I just hope to heck the quadrupler hasn't fried. Does anyone know of where to obtain a replacement?

Thanks
