i know these px suck but I found this locally and I'm tempted to get it, but can find NOTHING about it, even with the MO# info from the back https://imgur.com/HovvPWO https://imgur.com/k54TvR3 https://imgur.com/wXwRzpB what is it, who REALLY made it? Philco? RCA? if I cant find service info on it, it's just parts, I'd rater restore it. any help welcome! thanks!

SAMS lists a GE M939ACD:

The back cover and front control layout resemble this GE in a Shango066 video, which he identified as a CTC-15 clone.

thanks! I guess I was looking up the MO# in sections, not as a whole :/
that's why I got nothing

That thing's a dog. I scrapped one. The only good thing about it was the RCA 21FBP22 HI Lite CRT which was perfect! The CRT was used in a much more deserving set, a Zenith 23NC**. The last roundie Zenith made. The set isn't an RCA clone, a lot different. |

Personally if I had more space I'd be interested in picking that set up... from what I understand they were sort of like a portacolor with a transformer power supply and traditional roundy sweep circuits.
The worst limiting factor of picture quality in the portacolor was the coarse dot pitch CRT...the roundys didn't have that limitation... There's a LOT LESS GE roundys surviving than RCA or Zenith so IMO they are worth preserving more than the RCA designed off brand clones. The premium sets are nice to collect, but you can't fully appreciate a Dumont till you've experienced a Muntz.

Well, it's about 50 miles away from me, much closer than the stromberg carlson x-21 was, so I guess it's worth a try!

The GE Portacolors had two different CRTs: 11SP22 and the 11WP22. The early 11SP22 had the coarse dot pitch and the later 11WP22 had a much finer dot pitch - a much better picture. I owned one of each.

The AC chassis set is a bit different using 6AU8's in the color circuit. It's worth looking the schematic! IIRC, they made a rectangular set with a similar chassis. |

Electronic M, your comment about not fully appreciating a DuMont until you have experienced a Muntz reminds me of my first high school job in a garage. A 1959 Rambler came in and I got the job to fix it. I groused a little bit about doing it and one of the other mechanics said I couldn't appreciate working on a Lincoln until I worked on a few Ramblers! He was right.

The CA chassis had a CTC15 clone look to it in many ways but GE revised some most circuits to use their tubes. i.e. 6BH11, 6FM7 etc.
I saw one of the CA or CB sets on an episode of "Mister Ed" when Wilbur brought home a color TV one day, in an Italian Provincial IIRC.

I trained on a CX chassis, almost 50 years ago. It was RCA made, and seemed to be close to the CTC-12, with a few elements of the CTC-15. I think that was the last RCA chassis that they used.

well, I'm close to having it in my paws!

It's mine!
https://imgur.com/6uhmLi7 very bad cataract https://i.imgur.com/VuWhH0y.jpg https://imgur.com/vSwF40g https://imgur.com/Yty9iP5 reg cap is loose fitting, falls off easily. https://imgur.com/N9dESJM https://imgur.com/b1TBULo https://imgur.com/rQgBKXh now that is VERY stupid... rather than replacing a bad socket, someone soldered the wire to the focus pin of the CRT? WTF? https://imgur.com/58xIKOB blue is a bit low, but the CRT is not dead, not as strong as the one in my CTC-16xl, but could be worse. gonna let it sit a bit and wake up
