The O/P stated, there was no continuity across the power input. I don't think the power transformer primary would open, without making a burning smell. I don't remember a line fuse but it might have one of those surge limiting thermistors.
What is the chassis number of the set?

I, personally don't go by model names! RCA seemed to use the same name, years later, on a different set. Chassis numbers are all that count to me. I looked up the CTC4 schematic and there's nothing in the primary circuit, but the switch, transformer primary and the AC input, plus a couple of line filter caps across the input connector.

Thanks for the replies. It's a 4A, late run with all the mods done at the factory.
Hoping to get to it as soon as I finish restoring my daughter's HH Scott 130 preamp. Not much between the line cord and the xfmr, just the switch and associated wiring. Needed to do a sound trap and ratio detector alignment anyway.
