1966 RCA CTC21 Color Combo TV Chassis Vertical Repair on Jig One

Vintage tube color television diagnosis and repair now with followup / shango066

[@peterfairlie2296]

As a kid who watched color TV in the late 1960's I have fond memories of the TV repair man visiting our house just about every month to change tubes. On one occasion I was watching Road Runner and the picture went black and then smoke started coming out of the back of the TV. I though it was the work of the wacky Wile E. Coyote and called my Mom to the rescue !

I love these old American classics, I still use a couple of them to this day, I'm watching this video casting from a Chromecast on a 1971 zenith 15 inch tube series string color set, I'm not shocked that it dials right in because these old TVs everything is adjustable that vertical dialed in and made a perfect circle they're forgiving so that you can keep them running it's a non throwaway device!

Shango demonstrates the frustration involved in repairing these older 1960s high hour sets. Exceptional repair man! You (and Jordan from San Diego) are why I subbed to watch vintage TV's get diagnosed and repaired properly.

[@mr.classicalmusic5607]

Almost everyone smoked in the 1960's. I enjoy your videos.

[@vhfgamer]

I have a love hate relationship with smoker tar on electronics. On one hand, it really sucks to clean off. On the other hand, it preserves the metals and keeps corrosion at bay.

TV spaghetti heaven, these odler TVs are beauties to behold and I pay homage to the designers and builders of these beasts

Good job! Thanks for explaining the pharma ad thing in the US. Makes sense. If you can't find a TV/radio tube ask me . If I have it it's yours. I pulled a lot of them and have a tester.

[@johnmadow5331]

I always want to have colour TV when I was a child in Thailand. When my mother went for school in Washington DC. in 1970. I alsked her to pick up the colour TV set from Px and shipped it back home without understanding that the set does not work in Thailand and can not be modified to work with PAL AM 625 lines-220V 50 Cycles. The set like this was very expensive for middle class American back in 1968. It cost about $900.00 with console and $50.00 delevery charge along with $150.00 home service warrenty . This price was in 1968 when the gold price was $40.00 an ounce.

[@gregorypeterschmidt620]

This is fascinating John, thanks for that history. I hope all is well with you and your family.

[@SierraJohn]

Would definenitely like to see a part 2. Great set. We went to the RCA factory outlet in Commerce and ordered that same model. A week or so later, RCA called and said they weren't taking any new orders. They were overwhelmed with back orders and had no idea when they could deliver. We ended up getting a Packard Bell.

[@richroggio]

[@2509498788]

Good show.. I'm always fascinated watching you work shango..

[@jamesstout3430]

Finished watching and saw you found a transformer. The 21 was a good chassis. RCA started the cost cutting by the time th 31 rolled around.

[@chetpomeroy1399]

That old set certainly has that bright characteristic RCA color! These early color sets from the 1950's-60's weren't quite as reliable as their black-and-white contemporaries, probably because the higher chassis voltages and the resultant higher heat levels generated weakened the carbon comp resistors, dried out the jelly roll electrolytic caps and created other problems. These issues were largely resolved with the advent of solid-state chassis sets about five years later.

[@adamwheeldon]

Shango Time 👍🏻

[@mikefinn2101]

Great moring video and love those so many products out there. Nice job on the vertical xfrmr nice job learned something very good. sure appreciate your time as you spend 10 times the hours on the set than the 1 hour showing this video. Also you need to wear gloves to protect yourself from the contamination on wires . Thanks Mike

[@directcurrent5751]

Charles E Stone in old La Habra hated RCA color tube-televisions with printed circuit boards. It's unfortunate that cheap computer fans were not a thing in the 60s and 70s. This PC chassis platform was a major RCA repairs driver. Dried out then baked to brittle. This became the Zenith HAND CRAFTED CHASSIS real quality advantage; that's how the Zenith marketing of a Hand Crafted chassis became slogan in that era.

[@ericbelanger6900]

Very good video. Thanks. Interested in part 2. This convergence thing is very mysterious to me. 👍

[@MaxStax1]

I still have a model i inherited from the folks, that looks just like that in my living room, same controls and the cabinet looks the same. My parents purchased it in 1969. The one i have has a high quality record player with a lighted strobe speed adjustment and AM/FM radio tuner with awesome speakers. We had the TV tube removed and replaced with wood shelves years ago and use it a storage cabinet as the front panels slide across and cover the front all the way. But the record player and radio still work fine. I had it serviced a few years back in fact. It's just a nice piece of furniture.

[@mjg263]

Great job on a tough repair. Would love to see a part two with the chassis aligned in the actual set someday if you can find time, too bad it didn’t hook right up and cooperate for the owner.

[@joes3485]

The CTC 21 chassis went into the most expensive models that RCA made that year. At the factory they installed test selected CRTs ,which, from new had the best sharpness, focus etc. that the chassis could deliver. there may have been some extra time spent on the IF and Chroma alignment too. If the CRTs were ever changed, the set never again had as great a picture as the set started out producing. CRT quality can make a tremendous difference in the overall picture and color. Some of these sets also came with multi-function remote control circuitry.

[@ajwindmeyer2272]

Mmmm... Nothing makes my day more than Shango testing crapacitors.

[@jdollinter]

Wow, I bet this one cost as much as a good used car back then. We would have loved to win this in a contest but no way could we have afforded it back then. We had our RCA b/w floor model until the early 70’s and I have a photo of it from ‘69 with my older brother home from VietNam.

Thats when TV's 📺 were at their greatest. It's a bonus, if this happens to have a record player. One shaded pole motor must be for UHF. The other is probably for VHF. Them could be hand ✋️ made circuit boards. Better than today's flat screen TV's 📺. Your friend, Jeff.

Great repair of that line output transformer, not an easy part to change.

[@douglashoff95]

The chassis that were combined with a stereo used solid state audio and the stand alone CTC21's used the tube audio. I worked for an RCA dealer at the time these were fairly new.

Color vacuum bulb TV's are a trip. I remember messing about with my parents RCA new vista 27"

[@eeengineer8851]

Folks had a 1969 RCA 21" budget console. It must not have been the most reliable as I remember as a small kid the TV man coming out fairly often and even once I think he took it back to the shop and we had a loaner. They traded it in for a new solid state RCA 21" in '75 or so.

[@doogie812]

Yes that transformer was the same for all tube type rectangular sets. I would have thought you would have had a downer chassis somewhere. 19" & 23" anyway. Back in the day I had stacks of RCA chassis to scavenge parts off of. (Most with smoked flybacks). A bad CRT and a smoked flyback would = a trade-in set. :)

[@111000100101001]

Good workaround of the bad vertical transformer.

[@Seiskid]

Its a bit of a distance, but would love to see a part-2 on this set. Be a shame if the tube has failed. Had to think about the delete comment. Think I understand it. If its what I think it means, totally agree. Here in Aus we don't advertise the big P's products, but the mejia still won't say anything at all against them.

Absolutely brilliant video !! Just subscribed and liked ! looking forward to part 2 !! Back in 1986 I had a tv called a porta color I think it was an RCA , anyway it developed issues and I took it to a technician , he fixed it but called it a monstrosity of wires going in all directions !! I still remember when turning it on it made sounds that sounded as though it was a portal from hell !! lol !! I still remember watching Bonanza on an old Zenith or RCA TV a round picture tube set , wonderful memories !!!

About the H-Kr short, maybe you could use a separation transformer to float the Heater from the ground. I think you've mention it in the vid where you discover this problem, but you seem to 'yeah, nah'-ed it without explaining why you'd give it a pass. Could share more details as to why? Realistic wise, I've EOL-ed a 29" red filament by trying to blow it apart with a capacitor. Tho I did saw someone did it on modern sets. Been enjoying you contents for 4years now. really enjoys all of them.

I was able to go out and setup my long wire tower out on the field outside in the farm lands; I could hear WWV on 10Mhz and 15Mhz but it sounded like it was on the other side of the planet.

Any chance there is a shorted convergence rectifier? Or some other fault on the convergence board? Might also explain the transformer failure. Zenith had a problem with convergence rectifiers for a time. I believe there was a TSB about it. Great video as always!

Just FWIW, there's a small electrolytic across the emitter resistor of the audio out transistor that'll go wonky and cause a low-volume condition. .

Shango what do you do with the chassis high voltage second anode when using the electro-static setup set? I saw the anode cable hanging out there but….

[@skullheadwater9839]

I figured the gloves were either to keep the grunge or arcing high voltage off. Not that those playtex dishwashing gloves are rated for 20kv but it would be better than not having rubber gloves on.

Hello Shango I call you Shango I haven't caught your name. I have an idea about pocket radios. If you have one that has a cremated audio section take all the audio components out and install test leads to the final 455kc IF transformer and it can be used for an IF source 👍
