Found an RCA CTC5

[Penthode]

I got around to pulling the chassis on this set today. It is pretty well preserved with no tar on the HV components.

I looked at the power transformer(s) on the main chassis and second chassis. The main chassis mounted box is indeed a transformer and not an empty box. This being a 25Hz set, it appears as if the outboard transformer augments the main chassis transformer. I'll trace out the power supply circuit to see what modifications the Montreal factory did. Perhaps the Toronto Reference Library has the notes for the Canadian version of the CTC5-P?

The "Series 700 Notes" posted on the earlytelevision.org website suggests that to service the set, extension cables be employed between the removed chassis and the CRT. I am sure this has been discuused before in this forum: does anyone here know of the thread?

The cables look as if they should be easy to fabricate except for the convergence socket and plug. Does anyone have an extender to loan? Or alternatively, does anyone have the socket and plug to spare from a scrapped CTC5 chassis?

Cheers, Terry
