1963 Zenith 29JC20 restoration

[Zenith6S321]

Here are three pictures of the Zenith 29JC20 playing the Wizard of Oz. For comparison, here are two pictures (not quite of the same DVD frames) taken on my 21CT55 from a couple years ago with my same cheap camera. The Zenith has the 21FJP22A while the RCA has the 21AXP22A. I guess I would have to do a better job of getting the black and white tracking and the color tracking make a real comparison.

Many thanks for all the restoration suggestions and especially to Findm-Keepm for the ferrite cores. Two are now in the Zenith replacing broken IF and convergence cores.

I have been sensitive to narrow band R-Y, B-y chroma verses wide band I,Q chroma since I got my 21CT55 up and running. This was my observation of picture quality based on a side by side comparison with a CTC 4.


When I bought my 21CT55 for $50 in '64, I brought it into the house after I got it working and ran it along side my Dad's old CTC4 he left me. Both had 21FBP22s so it was a good comparison of narrow bw color R-Y B-Y vs. full bw color I Q. The extension of full color into fine detail on the CTC2B was startling! Color persisted in fireworks until extinction which I never saw before. The CTC4 fireworks turned into white long before extinction. The CTC2B carried full color way into the shadows, the CTC4 went gray to black. I kept the CTC4 in the house for the kids but brought the CTC2B back to the garage workshop for further study. Ease of working on the chassis and CRT "forced" me to destroy the cabinet and configure the remains into the vertical chassis configuration I am blessed with today. That’s alright with me. I respect the original CT restores but that’s not my thing.

Thanks for the kind words guys. Your assistance to overcome difficulties with these old sets really helps.

I can only hope that my efforts give the results that your skills brought with your Zenith!

That Velcro strap is called One-Wrap. It has hooks on one side and loop on the other. It work great for reusable cable straps instead of zip ties. I've used it for all sorts of things and once it's stuck to itself it's fairly strong.

That came out sweet. I always thought roundies had
the best pix especially with the older movies & anything period
from NBC. Bonanza will look even better than the Wiz.

The more I watch this set, the more I like it. The picture does not have the detail I see in my 21CT55, but it does have the full range of colors and a nice range of saturations. Its a pleasure to watch.

I'm impressed with the picture quality no matter what - Wizard of Oz, shows well! A pleasure to view, thanks.

If it is not too much trouble I'd be interested to see pictures of the tuners from inside the cabinet particularly the UHF tuner.

Here are the two pictures I took of them when I first started on the set. The first picture shows the VHF tuner from its right side (picture tube side when mounted in the set). The second picture shows the UHF tuner whose shaft is at the same level as the VHF tuner when mounted in the set. When I got the set the tuners were not mounted and it was missing its UHF tuning dial. I only use the VHF, which works quite well, so I'm happy. I can take more pictures of it mounted in the set if that's what you are looking for.
