Steve, the hor osc coil broke. Can the little red wire be soldered together and repaired? It broke at the base. The core is intact. I have a soldering station with a thermostat for the iron.

Zenith nut, Not to overstay my welcome, but here is the tube layout for the CM CMC-20 chassis.

No stay as much as you can! Just looked at whats left of the tube chart on the hv cage and it calls for a 1v2 focus rectifier not a 2av2 listed in the cmc20

Rca ctc 16 uses a 1v2

I noticed the CTC-16 as I posted. And the different focus tubes as well. Perhaps a production change on the layout chart. The tube complement list also has the 2av2 listed. Checked my RCA reference book and the 1V2 & the 2av2 are not listed as interchangeable. I have no experience w/these "later" model roundies. I would suggest that you repost or re-ask your questions to VK. Plenty of folks w/CTC-15's and if you're lucky a CM clone.

Best in the new year,

Hey Alex, I just now returned to my computer. I suggested VK color tv section as you did before. However, you did fine logging on to The Vintage TV Collectors site as well. I read your inquiry about the blue lateral magnet. You received the proper response. Hopefully you'll find the original or a good replacement. I also hope you received a reply on the hor osc coil. I'll look forward to viewing your progress on the CM.

Best,

Thanks Steve.

I have a friend who has a Curtis Mathes roundie combo unit that chassis was pretty much designed right after the RCA CTC 16s

The set appears to be a cross between a CTC16E and a CTC16X. All the 15 clones used a voltage doubler.
The 16E used a 1V2 where the 16X used a 2AV2.

The funny thing is, is that this set DOESNT use a tube focus rectifier. But it lists one on the tube layout. Theres a mount cut out in the hv cage for one too.
