If they wanted to be realistic, They should show at least one RCA with pva rot! When I was servicing those things in the seventies they were already looking bad...
Most people found it difficult to purchase a new color tv back then (at least around here)and bought second hand roundies and late 60's stuff for their homes.
There was one customer I had that didn't get a color tv until 1981 when I sold him a CTC 22!
As a matter of fact, That set came from my first ad I placed for non working sets back then!
I paid for very few of them, Most of the time the people would gladly give them to me just to get them out of their house!
This was '81 and I was getting CTC 7's through 16's regularly, They were still in use until then!
Back then I hated the round sets because they looked so old to me and were not worth as much for resale! When I would go to a house to pick up a tv odds were that it was one of those, I had so many that I started storing them at my Uncle's house (and others!) Earlier this year, I finally got the last few that were left there by me in the eighties and gave several to Doug.

Rented the movie Toy Story 2 today. There is Predicta Holiday in it owned by the story's bad guy. I realize it is animated, but they did a pretty decent job making it look the way it's supposed to. In fact, it plays pretty good to. This one plays B&W, so at least they got that part right!

BTW... the movie is pretty funny. The one liners really cracked me up! The bloopers at the end were hilarious!

Charlie,

The picture on your CM roundie looks really nice! Is this the one you restored emission with temporary increased filament voltage?

Thanks Rob... yes that's the one I cranked up to 8 volts for a few hours. I was really amazed at the difference in the color and brightness. Here is another shot from the same movie. I have really had a blast watching these computer-generated animated movies on this TV.

captainmoody,

I know the feeling of having to make do with used stuff in the '70s--I did a lot of that back then. My first color TV was a second-hand Sears Silvertone roundie from 1964. Got it in 1970 from a man in my hometown who had had the set in his garage for years. The set needed very little to get it working again (the circuit breaker was bad, so I just bypassed it; then the push-pull power switch on the volume control went West, so I bypassed it as well). I was able to get all three network stations from Cleveland reasonably well on the attic-mounted antenna in my house at the time (and later on rabbit ears when I moved closer to town in 1972); however, I never did get the convergence right, even though I fiddled with it as long as I had the TV. Later on, I had a hum bar in the picture I couldn't get rid of, not to mention a problem with the color sync going out every now and then.

The set finally bit the dust for good in 1973, when the video-output tube socket broke out of one of the circuit boards.

I would not dream of taking the back off of my present RCA XL-100 19" color set, let alone tinkering with the circuitry. These modern sets are beyond my understanding, although I understood tube sets fairly well 30+ years ago.

This must be a common problem in vintage sets. I've got three sets that the old power switch had to be bypassed with a toggle or push button switch.

The manufacturers cheaped out on the volume control mounted power switch. What they should'a done is install a motor/fan switch properly rated for a 1/2 HP inductive load. That is exactly what this tubed color chassis represented!

In an effort to make the switches that still work on my vintage TV sets and radios last longer, I turn them off and on with the power disconnected. I then use a sperate external switch to apply power.

The hope is that this will at least reduce the damage from internal arcing.

They finally wised up by the time they got to the CTC-68...it has a factory mounted microswitch behind the volume pot that is operated by the push-pull action. For some reason, though, some later RCA sets used the cheapo push-pull switch with the resulting switch failure.

On my GE round color the volume shaft pulled right out of the pot/switch one time I turned it on! I now am using a power strip to turn set on/off...will replace switch.

Somewhere I have read about fires caused in CTC-16 and similar sets by arcing in the switch causing heat/sparks, and setting plastic gears on fire in the tuner and then dripping flaming plastic on the speaker cone and setting the set on fire.

yes, that was a serious problem with all of the early CTC series chassis that used a pull on-push off switch. i have personally encountered five of these sets. fortunately, the customer caught on to what was happening when the switch started burning & took steps to put the fire out. i was able to repair all of those sets.

I had a problem with my CTC-12; bad enough that the switch was bad-there really isn't too much to it-but some numbskull had glued the knob on, had to destroy the knob & what was left of the switch pulling it out. I really wanted to switch to a newer style which uses a perpendicular mount slide switch, since I have a few used ones and they look more solid, but this set has a shaft something like 10" long & the newer ones needed about another 1/2", lots of NOS shafts here in a box but all much too short. Oh, well, for now it works. From now on I'll have to pay attention to this hazard, maybe some sort of fireproofing!
