Waaaaaaahh...Its in New-effin-Hampshire...Might as well be on the dark side of the Moon, even if I could afford it in the 1st place....There must have been a LAW that they couldn't sell color TVs in the South til about '64 or so...

Other than being mahogany, that is the same model as the one I just finished restoring. Interestingly that one has the word "Color" on the bottom of the safety glass whereas mine did not.

There was a 5 at the ETF this year (well, a chassis and cabinet) that also has 'COLOR' silk screened onto the glass, I wonder how common that was for these sets? The earlier ones never had it, and the later ones had 'COLOR' right on the CRT plastic mask. Wonder if the words being printed onto the glass was an in-between thing?

Never saw any like that in the St. Louis area. That had to be expensive.

Wow, she's a beauty!

Mumbling in background: "It's only 1,002 miles from Starlight to Salem. Do we know anyone who lives lives up that way?"

Not quite so- I recall seeing color sets (probably RCA or RCA chassis Philco) on the floor at Broadstreet Furniture in Kingsport back in the fifties. The CTC numbers and my age were still in the single digits then. I have had a CTC5 (looked like the one listed) and a CTC9 that have since passed through my hands. I still have a CTC4 that I bought in 1966 from a gentleman that bought it new in Ohio and hauled it back in his truck. I installed a RCA 21AXP22 from Radio Electric Supply here in town- first CRT replacement of many that I performed. It has been in storage since 1970- think the caps are still good?

Mark recently restarted his CTC-4, and it still works on all original parts. Mine sure didn't though, it was run into the ground by the PO who had owned it since new. It sat in her home in Indy being repaired whenever it broke up until 1976!

I have a story about that glass. I bought a CTC-5 back in 1960 and fixed it up for my own use. Once, when removing the glass for cleaning, I chipped it. I called the RCA distributor and in spite of the set's being fairly young at that time, it was no longer available. It was slightly tinted, but I settled for a piece of laminated glass sized for me by a glass shop. That's how it went for years.
One night I went to the RCA distributor's place in Portland Maine (Commercial Distributors) for a color TV servicing seminar.
On a desktop was the glass I wanted, complete with the "COLOR" logo. It turned out that nearly every desktop in the building had a CTC-5's safety glass on it! When I tried to buy one, one was gifted to me.
To this day, the clear laminate replacement I had cut is on top of my living room TV's cabinet being used as a protector.

Yeah, just bein' facetious-My cousin Johnny Harrison-Owned Harrison's Bootery-had a light green colored metal-cased roundie color set when I was a kid-I can remember coming up to see it-Color was still a BIG deal then-& my grandad bought a woodgrain metal Zenith roundie about '65 or so-I have that set now. Its currently inoperative.

Nick,

You are correct that the early CTC-5 models did not have "COLOR" on the safety glass. A later production run change, until the end of CTC-5 production, had "COLOR" on the glass. Other than that change, the mask on the CTC-5 was the same for its entire run with the exception of the CTC-5 " entry level "Special" series "Aldrich" model
deleted the black painted surround in the mask. The word "COLOR" embedded into the mask, I believe, was first seen on the Mark Series CTC-7 models.

Actually, I was referring to the later CTC models but that's interesting. My CTC-7 has the plastic mask with 'COLOR' on it, where the only earlier model I've seen with it on the glass was CTC-5.

I'm curious. What would be causing the wave in the vertical color bars and crosshatch lines?

The owner said the color bars and cross hatch patterns were being played back from a VHS video tape, rather than a standard piece of test equipment, hence the hooking and wave. Also, he said the actress is Helen Mirin in makeup.

Ahh...that makes sense. Thanks for pointing that out.

Whoever did the convergence on that one must know tricks I've never heard of. I have slaved over converging my two CTC-11s and neither one looks quite that good on the far edges.

Someone asked a question if the phosphors were replaced when the tube was rebuilt. In rebuilding a color tube, the phosphors are impossible to replace due to the fact that you cannot take the tube apart that far without ruining it.
