Of course, I can't take 100% credit for that one....he might have seen it before I did.

Please post the chassis and cabinet serial numbers so we can add the set to our database.

Good thread about your restoration, Zenith 6S321! Problem is that I don't have all the nice equipment that you do. I do have of course have a digital VOM, and a 20 MHZ scope, HV probe, color bar generator, a variable isolation transformer, variac etc, but I don't have things like a B&K analyst, or sweep and marker generator. Another thing that I don't have is a test picture tube jig, and I'm not even sure that would work with a CTC2. Usually, I change all the electrolytic caps, the old wax capacitors, and any out of tolerance or burn't resistors, but alignment is not one of my specialties, except maybe adjusting the sound detector, 4.5 trap, or 3.58 osc. coil to get the color to lock in. I have never re-stuffed the cans, as I usually just find room underneath the chassis. Maybe it's time I try my hand at re-stuffing them. If the selenium rectifiers have not already been replaced with diodes, I plan to do so, putting in appropriate dropping resistors. I used to have an old Eico sweep and marker, but it was so unstable, that is was useless, and got rid of it many years ago. This project is going to turn into quite a challenge, and possibly buying some new old stock or good used test equipment. (E-bay is my friend!) It would be nice to have or make up some cables so I can hook up the CRT while the chassis is on the bench. That would make servicing it so much easier. (Clip leads are great, but not in this instance). I do have a couple of yoke adapters though. I have repaired TVs since 1972, but I have never taken on one as old and involved as this. Wish me good luck. Walterbeers

Wow, what an amazing find -- and with a good CRT to boot!
I look forward to hearing about its restoration. My thinking with a set like this is, you may never find another one, so take your time, do it right, and enjoy the process. Regards, Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html |

Awesome find. A pretty rare set to find with a very lucky to find working crt!!! That looks like the maple version of my rca ctc-9 Caulfield in the background also. Great sets.

from facebook?

I once mentioned to a co-worker that when I was kid we only had B&W TV. The response was "black and white"???? "I don't think I've ever seen one!!!" and probably not, as he was only around 16 or 17 years old. |

The Story.....
We totally lucked out having something this rare pop up in our backyards. The set was located in Glenwood, Iowa. I am an insomniac, and check facebook and craigslist whenever I am up. I saw the posting and literally 2 seconds later Tim posted it on my FB wall. ( Tim.. THANK YOU!! I think it was the shock of seeing it on CL and the "push" from Tim that made me immediately contact the seller) I debated for a hot minute to purchase it for myself, but my good friend Walter had been looking for a CTC-4 for ages, and he is better equipped to repair something this old and rare. I knew if I kept it, he'd have to do most of the work anyway, and funds are tight on my end as I just had to pay $2700.00 to have a dead tree removed. Anyway.. obviously this is older than a CTC-4 ( neither of us thought we'd ever find anything older ) I had a CTC-4 that I sold to Mark Mason some years back, as I knew he'd appreciate it more than I. Just like I knew Walter would love this set. I called the seller, and I felt like I was on a job interview. I think what clinched the deal was I said I would send him a video if we got it working. I made arrangements to have it delivered, and he texted me about 3 hours before he hit Omaha. I called Walters wife Kathy, and met him at Walters house and had it dropped off while he was at work. Let me state that I forgot how HEAVY these 50's color sets are.... haha. Anyway, we'll appreciate any tips on this set thru VK or my tv friends on facebook. |

Wow, simply incredible! It's nice to know that sets like this can still be found in the wild. Congratulations
I also advise you to proceed slowly and don't try powering it up until you've thoroughly checked out the power supply and sweep circuits. Looking forward to the restoration thread. Best of luck. -Clark |

I haven't done anything yet with this set except check the CRT and open up the HV cage, finding a cracked rectifier tube. I intend to take it slowly. First I'll check out the power supply, and sweep circuits, and of course bring it up slowly, monitoring the B+, with the horizontal output tube removed. If I get some audio noise, that will be a good sign, then maybe hook up the horizontal, bring it up slow again, as I monitor the horizontal osc waveform and high voltage. I am hopeful the flyback is ok, runs cool, and doesn't smoke or anything. Time will tell, and I will keep everyone posted as to it's progress.

I THINK...a 3A3 will work in place of that 3B2 ..in case you do not have the original.

Walter, you may want to check for shorted HV caps in the HV cage. The largest one in my set was shorted. With rare sets like this I think it is best to proceed cautiously. Burning up a flyback would really ruin your day.

Got Audio
Well, some good news, (well sort of anyway), I removed the horizontal output tube and brought the AC voltage slowly up to 75 volts, and I got noise from the speaker, and had about 250 volts at the top cap connector for the 6CB5. So I hooked up a converter box to the antenna terminals, went to channel 4, and I did have sound. The selenium rectifiers are still in circuit, and one of the fuses had been bypassed with a clip on fuse, which was actually broken. So, for now I just clipped in a 3 amp pigtail temporally. Just getting sound raised my enthusiasm. I did find out that the fine tuning knob is broken, so if someone has one that would work as a replacement let me know. I'm not going to do any more with it today, as I have other stuff to do, and I'm getting really tired. Been up since 5AM, my usual wake up time. A 3A3 won't work, the 3B2 is a small 9 pin tube with a top cap.
