I think some late CTC39's used a 25V tube.

Well, browsing ads and catalogs I noticed that RCA didn't use the same cabinets across different chassis. I did some hunting and found an ad from 1972 (I think) displaying that exact cabinet and control layout (no power bar, one button above the two pots in the door) - crossed the model number in the ad (GR670) through the Sams index and came up with the CTC39 chassis.

Wow I learn something new every day I guess. So I did have the early CTC-39.

Yep, a Muntz color set from 1965....be patient, I'll start a thread about it

I have a LOT of cabinet repair to do on it so it'll be interesting.

The 25V" set in the cabinet/control panel design shown here is used for the CTC-39 illustration in the RCA field service guide. The CTC-39 I have is in a metal table top cabinet with a 23V" tube and looks like a late model CTC-38.

Are you sure the set shown in this ad isn't a solid state model? I have a set which looks exactly like this at home which is an XL-100 solid state (CTC-46 or 48?) which I think is from 1973.
The tube type CTC-39 set will say "AccuColor" above the volume/brightness controls but it looks like the text on this one is longer than "AccuColor" and may be "XL-100 Solid State"

Here is a video of my solid state set:

My grandmother bought a CTC39X new around 1975, possibly a clearance sale item (store making room for SS models). She also got the service contract, found the paperwork (they replaced a pilot light). She watched soap operas and regular prime time OTA on it a lot. My father (grandma was his mother in law, and they had the standard issue relationship

) and I replaced tubes, the horizontal output and damper IIRC. We ended up with it in the mid 80s. The VHF tuner didn't work, but UHF did work. Probably a dead VHF local oscillator tube. MY brother tossed it...

I haven't seen it in person - I can only refer to my earlier post as to how I arrived at my conclusion.

Actually, Moyers just had a 119834 up on eBay - and some lucky individual outbid me. My '39 fly is still good, with 190-200mA current, and fused, but I' was hoping for a spare. Fly 308's and Fly 312's show up on eBay occasionally, and some were offered in ETF classifieds last year, so I've not given up entirely.

Cheers,
