Post those 1950s color roundies

[miniman82]

It's a 21F(B or J)P22.

A little holiday cheer.

When this thread started I did not own a single roundie. Now I own 4 sets. This is an RCA CTC-7 Worthington from 1958. In the corner was a 21CT55, buts currently being restored so we put a small Christmas tree in its place.

Show us your early color sets. :-)

I thought I'd never find a roundie. But the TV Gods shined upon be, and I was blessed with a 1963 Admiral combo. Now just to get some RCA and Zenith roundies. Rare as hen's teeth in these parts.

I posted this on my own thread when I first got it, but I thought I'd add it into this thread! It's my 1959 RCA CTC-9 Caulfield in near mint condition. I've yet to restore it, but will soon..

The rest are out in the shop and I have one set in a museum in California.

Being originally from Wisconsin, the "formerly Packer Land" in my handle, GO PACKERS!

Very nice set.

Radiotronman: I missed out on the Caulfield that Doug was selling on eBay about two years ago, same but maple cabinet. Very nice set.

Here's the CTC-5.

Gory details:
This is a Super chassis, arguably the worst early 21 inch set RCA ever made. The design high voltage is only 18.5 kv, making it a real dim-bulb set. I used to have a 21FBP22 glass tube retrofitted in this set, which helped a bit with brightness. The current tube is a re-gunned 21AXP22, so it is the original tube with wide color gamut (especially the green), but it is even dimmer. Also, the particular 21FB that I had gave almost perfect convergence. This regunned 21AX seems to have the gun rotated slightly out of true. To get the corner convergence, you need to to rotate the convergence coil cloverleaf about 15 degrees. You would think this might ruin the purity, but it doesn't. However, I haven't looked at the beam landing with a microscope yet.

This set has been sitting for over a year without being tested since it was shipped from Illinois to Arizona. When I fired it up today, the only obvious problems was that the yoke had shifted and had to be pushed forward to get purity; plus, the red dynamic convergence is way off. [Oh, and the power cord got lost somewhere.] The corner convergence is affected somewhat by that apparent gun rotation. I will be doing some of that never-ending convergence chasing now, I see.

The color actually looks somewhat better in the photos than it does to the naked eye, except for the reflections from room lights. When I turned off the lights, you couldn't see the front of the cabinet. If I hadn't tried to to get this all done this afternoon, I could have fiddled with shooting the CRT with the lights off and superposing that on a good shot of the cabinet.

I will also post a pic with Christmas decorations on top over in that thread.

Edit: When I first fired it up today, the width was inadequate. I am running a variac into an isolation transformer with multiple taps. I found out that the direct side of the isolation transformer Where I have been plugging in the line meter does not have the same voltages as the isolated side. The middle tap is especially different; the high and low taps not so bad. So at that point I just cranked up the variac until I had full width. I will have to put together a two-prong power strip setup so I can plug the TV and the line meter into the same tap and see what I really have.

My 1956 (1955 model year) Hoffman Colorcaster:





This was a gift from my Grandpa Burkhardt, the grumpiest old kraut to ever walk the face of the planet. He's a pain in the ass, but we love him and keep him around anyway

I saw the set on eBay, and unbeknownst to me, he tracked down the seller and offered to buy the set before the auction ended. I then paid to have it shipped from the SF Bay area back to Michigan. I then sold the set to another local collector to go on an ill-fated adventure with a CT-100. I sold the CT-100 to a fellow in Pennsylvania, made a tidy profit on that deal, and ultimately ended up buying this set back. I'll be six feet under when this Hoffman goes on the market again.

21AXP22 is good, the strongest I've ever actually seen, and the chassis is recapped. It's now passing good clean video, just have to track down some arcing HV cage.

My 1961 CTC-11 chassis Philco. A bit too "new" for this thread, but I just moved it up to the living room and wanted to show it off

An excellent example of why the I and Q axes were chosen - practically no Q axis details in that scene at all.

That Philco is gorgeous Tim!

David, somehow, I hate you. No, just kidding. Very envious and a wonderful set, thanks for sharing the picture.

My only 1950's Color Roundie is my CTC-7B, "The Sanford" from 1958, it's the oldest (to date) color set that I have ever owned, or worked on. I still have to re-cap it, and replace it's CRT, hopefully this winter! I got it basically working, after I bought it from the original owner's Estate Sale, in Niles, MI, about two years ago. I had to replace burned open wires under the 5U4GB LV Rectifier sockets, and an open fuse. That got it going, but needs Electrolytics, and vertical and horizontal caps, as well as it's original and very tired 21CYP22 CRT. I was able to secure a good emission used 21CYP22, so it's on stand-by, waiting to be installed!
