Curtis Mathes Color Roundie ID
Hello,
Last night I dragged home a CM roundie. Theres not a lot to go on with it. Most the tubes are CM branded with date codes of XX-65. Has a RCA Hi lite 21FBP22A crt in it. Theres a chassis # of C20-1j i think it is. I will try to upload photos here. I may have to resize them. Maybe a CTC-15 clone? |

Front. A bunch of the controls like tone are sorta hidden under the bottom 3 controls

It's definitely a RCA clone. The type Horizontal, damper and vertical output tube will determine whether its a CTC12, 15, or 16 chassis clone. I'm leaning towards it being a CTC15.

Tony the damper is a 6dw4. Hor and vertical are 6fq7 and 6gf7. 1av2 focus rect. Should I try to get the sams for a ctc 15/etc or for this set specifically?
Also the diode bridge is mounted on terminal strips under the chassis, not on the pcb. I downloaded the sams for rca ctc 15 off the early television museum. Looks really similar except the CM uses a tube focus rect and the rca ctc 15 uses a diode. Last edited by ZenithNut; 12-29-2018 at 03:20 PM. |

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.

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, Steve Dichter Stevetek@webtv.net
