CTC-10 with remote
I picked up this set today. Saw it on CL last night and went out to get it this morning, sat in traffic for an hour and a half on Laurel Canyon, only to get to the store and see that it doesn't open for another 2 hours. I left my car parked out front, and walked to have something to eat, but still wound up just sitting in my car for an hour or so. I bought it, told them to hold it for me, drove to ucla to get one of my friends to help me lift it in and out of the car, a couple hours later, after lunch, we set out back to Hollywood to pick up the set, we load it in the back seat with the top down, and go back over the hill, sitting in traffic for another hour. Then we get here, unload the set, and I drive him back to ucla, and I sit in traffic again on the way back here. I spent the most of the day driving in bad traffic, but this set was worth it.
The CRT tests good on all 3 guns. The remote controls color and tint as well as channel and volume. It'll be a while before I get to this though because I want to finish a few other sets I already pulled the chassis out of first. |
Nice set!

Adam,
The set would not fit in the trunk of your car?:D polaraman |
great find Adam. I look forward to seeing it in action :yes:
|
Congratulations on that one!!!
I had heard wind of it on Wednesday from Dr. Dan, but didn't act on it. Where are you going to put that :scratch2: Charles |
On fitting lots of sets in a small space:
Not in the pics are my Zenith SC 300 and the 3 console radios currently in the bedroom.
And having the convertible makes hauling large sets a lot easier. |
Now I'm getting back into this set. First I'm going to repair the remote, after I took it apart, I saw that one button was cracked. I'm going to try taking it apart and gluing it back together with some epoxy.
Before I get going on this set, I have some questions on soldering on circuit boards. What should I be doing to avoid lifting traces and making a mess of the boards, is there a particular technique involved in removing, and soldering to the boards? Also what is a particularly good soldering iron/gun for working on the boards? I've never had any trouble soldering to the old style point to point wiring, but never really managed to get the hang of working on the circuit boards. |

Congratulations!! That thing screams class! Very lucky and nice find! Thanks for the pics of your tvs, now I know I'm not the only one piling them up like that!:D
|
oh wow ...gr8 catch and you have some marvellous things in your collection ...I note the CED disk player on the floor under one of your sets!
|
An' I thought I had "The Sickness" bad...Hell, I'm a piker...(grin)
|
It's great that you found one which haves remote control. I know back then remote controls weren't a common things!
|
Adam, I may have a few of those remotes, if you need parts. I'd have to look, but I'm pretty sure I do. Also, that takes a funky silver-mercury battery... You can use the later RCA remotes for functionality, and just keep a clean original for display if you want.

Those pics are a year old from February, since then I sold a few of those, and picked up a few others. Thanks for the tips on soldering the boards. That is an odd battery 4.2v, are those (or some equivalent) still available? The old battery was still in there, and actually had caused some some corrosion on the battery terminals I had to clean up. I fixed the buttons that were cracked, then cleaned, and reassembled the remote.
|
lucky dog! You have a color remote set that will probably soon work.
|
Beautiful job on that remote!

Removed the safety glass, cleaned all the dirt/dust off the front of the crt and the inside of the glass, and put that strip that says "color" back where it should be.
|
Which VS battery number does it take? Chances are it's a VS133, and there's an alkaline equivalent called the En133. Eveready recently stopped making them, but there's a cottage industry making them. Just check on the web.

This looks alot like the set President Kennedy had in the Oval Office.

The battery is VS163 Eveready E163, I looked around no 4.2v batteries, but there may be some 4.5v batteries that might work (or if I can find 3 small enough 1.5v batteries). After taking a good look at the chassis I can see a lot of repairs done before (mainly caps replaced). Also whoever worked on it before kept hitting wires with the soldering iron, melting the insulation in places, not so bad I want to replace them, but still I would have thought he would have been more careful on such a high-end set. That big replacement electrolytic on top of the chassis there, 80mfd 450v, is not actually replacing one of the power supply filters, but rather the 50mfd 50v cap which hooks to the contrast control, I wonder if he really meant to do that or just connected the wrong wire. The thermistor was broken and the wires were just twisted together there. Was there originally some kind of metal cover that went over the bottom of the IF board? It looks like there might have been something like that there that was unsoldered and never replaced. |

I read the White House was in disrepair, and falling apart. When Kennedy moved in, Jackie with her magic, made them spend millions to rehab, restore, and decorate the place. They were not too thrilled with her spending that kind of money, she wanted
and got the best material and craftsmen to do the work. Today they are glad she did that, restored dignity to the White House. Maybe she had the TV tossed out ? |
There is a series of pictures here: http://www.whitehousemuseum.org/west...ce-history.htm It looks like Kennedy kept the ctc-10, but Johnson had a unit installed that was 3 sets in one console.
The remote does actually turn the tint, color, and volume controls. I checked all the tubes. None shorted, or so weak that they obviously won't work. The 6AQ5 (audio output) was weak enough that I'll probably swap it out, and the 6EM7 (vertical) was slightly weak, but I'll probably see if there's actually any vertical trouble before changing it. Most of the tubes had been changed in this set over the years, it probably saw at least 10 years or so of service, many tubes have that more modern looking RCA logo on them. It is interesting to note that all the replacement tubes are RCA tubes, I think this is the first time I've ever seen anyone actually pay attention to the signs they put on stuff that say "use only ... tubes." |

I'm nearly ready to put this set back together. I swapped all the electrolytics and paper caps in the TV chassis. I replaced the broken thermistor. Checked the restistance readings at the tube sockets in the horiz and vert circuits following the sams, and only changed a few resistors that were only around 20% off anyway. I swapped that one 6AQ5 audio output tube, all the other tubes tested ok. This set looks to me like it was well maintained into the late 60s or even into the 70s, there were already some orange drops in it, as well as many tubes with that newer RCA logo. I also recapped the remote chassis, and replaced the selenium rectifier that was in there with a 1N4007 diode. It's strange how the plating is starting to come off of the top of the remote chassis. And I swapped the selenium rectifier on the convergence board for 3 diodes. The 3 things I haven't picked up yet for this set are still a battery for the remote, the metal piece that goes under the IF board, and the socket for the light that goes on the bottom of the cabinet (it was missing). But I might just put it back together and fire it up first, just to see what's going on.

a question, but this color TV SET you have found in the street or you have bought in a store?
|
I bought it at an antique store, but I found out about it because it was also advertised on craigslist.

today you can find 3 or 4 TV SET in a house. but 20 or 30 years ago a house a TV SET. |
Broken speakers! These two tweeters are broken (see pic). I might be able to solder some wire to the one on the left, but not the one on the right where that one wire is broken way inside. I looked in my stash of speakers but I don't have anything the right size. It's 3 1/2" 8-10ohms. Is anybody currently making anything that would work as a replacement?

I had this same problem with both a B&W RCA TV and a 1953 model RCA radio. The wires did break off of the speaker mounted connecter in my cases, but I was able to soldier them back. To fix both of them I drilled the remains of the old rivet out and replaced it with a machine screw and bolt.
As Andy indicates, this seems to be a weakness in RCA sets. |
It works. That pic is nearly like it was when I first turned it on, all I adjusted was the vert height. I haven't done any convergence or anything else yet. The power tuning does work, (but the tuner does need cleaning, I had to spin it around a few times before I got that good of a picture.) I can't fully test the remote yet without a battery, but I tried a Zenith SC600 remote, and the "channel higher" button changes the channel lower, and the "off-on" button turns the color control up. Also this set picks up a lot of interference from the DVD player, (maybe because of that missing metal plate from under the IF board?), I was finally able to eliminate most of it by getting a long wire and placing the DVD player several feet away from the set on the floor, and using a separate RF modulator rather than feeding the TV directly from the RF output of the DVD player. I'm currently running it on only one speaker (without those 2 speakers from my previous post) but it sounds ok.

Looking good Adam! Wow those are some deep reds! It came out nice for your first start up. Nice job on the restoration!

The picture stays b/w for about a minute before the color comes in. I'm going to try that chroma oscillator alignment like I did on my Philco which fixed this problem in that set. But for now I'm not going to mess with it for a while, at least until I dig up something for a battery for the remote and try and fix those speakers. Next I'm going back to the Philco, I finally tracked down a needle that fits the phonograph in that unit, so I'm going to see if I can fix the record changer. It works manually, but won't change records. |
I don't know what happened here, somehow I posted twice...
