May 3, 2015 · How RCA-Victor made color TV sets in 1959. Also, how the beautiful little RCA audio and TV tubes were made and tested and how the legendary "shadow mask" three-gun picture tubes were made. A must-see for TV and stereo lovers.
May 3, 2015 · Correct, and color tubes produced more x-rays than monochrome tubes, supposedly. I had talked my parents into buying a color TV in late '66 or early '67, and then that news broke, and my mom refused to have one in the house. So we didn't get our color set until December of '68. Steve: Thanks for posting the film.

RCA offered the CTC-4 television in five cabinets, named Haviland, Seville,Director, Cheltenham, and Gainsborough. My set is a Director. The second photo, providedby Steve Dichter, shows Directors coming off the assembly line. Priced at $895, the Director anchored the middle of RCA's color TV line for 1955. Least expensivewas the Haviland, with a m...
Like the CT-100, the CTC-4 can receive UHF as well as the standard VHF channels,a rather uncommon feature in 1955, when UHF stations were not widespread. The CTC-4 marks an interesting stage in color television development. As explained in my article on CT-100 electronic design, one can use differentmethods to demodulate (decode) the color informat...
While scanning craigslist ads one day, I noticed a rummage sale that included an RCAmodel "21-CT-852" television. RCA never made a TV with that model number, but the photo looked like amodel 21-CT-662U, the CTC-4 in a mahogany Director cabinet. I made a beeline for the sale, a fund-raiser for a local pet shelter. Here's my first view of theCTC-4 th...
After unloading at home, I got a look under the chassis. A few capacitors were replacedin the past, notably the pair of yellow electrolytics hastily wrappedwith black tape. I was told that this one-owner local television had never left the lady'sliving room. Apart from dusting, the chassis was remarkably clean.I wouldn't be able to start restoratio...
After doing a little more cleaning, I brought out my CRT tester for another check.The signs were discouraging: When I turned on the tester, the heater voltage dropped from 6.3 voltsto around 3 volts and the tester made a whining sound, as if its powersupply were unhappy. The CRT passed the G1-shorts and H-K shorts tests, butthe needle didn't move a...
Here's the top of the chassis after brushing off some dust: At the lower right you can see five electrolytic capacitor cans with black and yellowcardboard covers. These contain the main power-supply caps, C1-C4 and C6. Replacingthose will be one of my first tasks. At lower left in the previous photo are the two big orange selenium rectifiers.Those ...
The first step in restuffing the electrolytic capacitor cans is to remove theircardboard covers. After warming the cover with a heat gun to soften the tarryadhesive, you can simply pull the cover off. Cardboard covers provide shock protection on cans whose metal exteriors are not connected to chassis ground.As you can see in these photos, such cans...
Things in the high-voltage cage had looked OK at first glance, but in the course ofrecapping I removed the cage for a closer look. Uh-oh! The burned resistor wasn't visible before. A little nudge showed that it was actuallybroken in half. The 6BK4 HV regulator tube has a big plastic insulating crown that looksblackened and chewed up by arcing. This...
After hours of tedious recapping, I'm ready to apply power and the initial results are encouraging.The basic voltages look reasonable and the chassis produces good-looking waveforms. In thenext photo, I'm looking at a horizontal waveform with my trusty old B&K Precision oscilloscope. With a pattern generator supplying a color-bar signal, I also saw...
Voltages and waveforms are well and good, but without a usable picture tube, this TV willnever make a picture. Fortunately for CTC-4 owners, it's possible to replace the rare 21AXP22 picturetube with a newer 21-inch color tube. After I mentioned this in the VideoKarma forum, a generous fellowcollector across the country offered a 21FJP22 CRT that h...
