My new RCA CTC-25!
 

After 5 long weeks, I finally had an opportunity to go visit my friend Danny in Atlanta again. He had set aside a few things for me, including a 1982 Sanyo Betacord, but the real treasure was an RCA CTC-25 "Winslow." We powered it up, and it had a "passable" but otherwise lousy picture. It had an RCA Colorama CRT and the emissions were almost completely dead. He said I should leave it there for now and he would replace the tube and fix a few other problems it has. I'll be going back February 20th to pick it up and to go to the swap meat.

I believe you would want this thread in the "rectangular screen tube television" section although I am not a moderator. I like the cabinet style of this set btw. Is there an additional speaker behind that cloth below the screen?

There is only one speaker, and it is below the screen.

That is a sharp looking set, and compact too. Also nice to have a friend that changes CRT's for you. :thmbsp:

Yep, Danny is a super great guy and I can't thank him enough for this TV.

I like the looks of the control area on those era RCAs!

Moved to rectangular.... :)

In order to transport this set in the Buick, the CRT will need to be removed from the cabinet and reinstalled later. Any information on that process will be greatly appreciated, as I have never reinstalled a CRT.

General CRT removal procedure: Remove back of cabinet, unscrew main chassis and unplug plug-able wires connected to main chassis (note where they go), if tuner sub-chassis unplugs (haven't seen that on an RCA) unplug it or remove tuner sub-chassis from cabinet (there should be a piece of metal on the back of the tuner chassis that can bolt to the screws on either side of the cord interlock for safer transport...do that), remove main chassis from cabinet, set cabinet face down and remove screws/bolts that hold CRT in (usually at the corners), unscrew convergence board, if possible lift the CRT, it's mounting and neck hardware and convergence board out as a unit (it's usually an unnecessary pain to remove, reinstall and properly readjust the neck hardware), have a towel, rug, or some soft thing to set the CRT on ready so CRT face does not get scratched.

I recommend wrapping the convergence board and it's wires around the deflection yoke shroud so they don't flop around, and recommend bolting tuner to main chassis for the same reasons. Be careful things don't bump things on the boards I had to do a lot of extra work and parts sourcing to a CTC-20 roundy because a previous owner did not bolt the tuner sub-chassis on and let it flop about and damage things.

RCA made only one year of that channel selector and fine tuning arrangement, as they were trouble prone. You pushed in the channel selector knob for VHF fine tuning. The outer knob was for UHF tuning. Also you had to get the indicator lamps for the tuner from RCA, as no one else made them. Plus they were hard to focus properly. :thumbsdn:

Nice catch! Sold a number of that same model back in the day.:yes:

Preachin' to the choir again, but don't forget the two ground stakes on the far-right end of the chroma board need to be reflowed. That's routine on any CTC-12, 15, 16, 17 and 25. When (not if) one of those grounds lets go, it kills the heaters on the two 6GU7s. That allows beam current in the CRT to avalanche, which ain't good.

You're gonna remove and reinstal the CRT? :eek: Here's a tip that's better to learn now than later: After a CRT replacement, the whole jug will gradually begin to tip backward, creating a larger and larger gap between the mask and the top of the CRT. We learned quickly to thoroughly tighten the steel band securing the CRT to its 'mounting ears'.

Yeah, Danny explained to me all the issues they had with this tuner. I won't be turning it very often. I'll probably just leave it in channel 15 all the time.

Old coot88, noted. Thanks for the info.

the good thing now tho... since it will either have to be run off a converter box or VCR, at least the tuner won't be an issue. They were a bitch in the day tho. Not a bad set otherwise. That chassis looks pretty clean. Did your friend clean it up, or is it "as found"?

This TV will be receiving channel 15 UHF. Possibly tied in with the VBT200. I'll have to ask him if he cleaned it up or not. But I agree, yes it is remarkably clean.

I absolutely cannot wait to bring this set home! I'm considering installing a small computer fan to help cool the flyback. I could probably just make do with hooking it up to a 9 volt battery when the set is turned on. Your thoughts?

I'm glad, someone agreed with me regarding the tuner issue.
It wasn't the actual tuner, but the crazy gearing design.
The chassis design was good, but they were hard on flybacks.
I have a year newer set, where there was slight differences, a CTC28. By the looks of the set, it appears that it was maintained under contract, by RCA Service Company. It has a rebuilt CRT, stating RCA Service Co.
It seems that they were getting their replacement CRT's from a third party supplier, instead of RCA parts devision. :scratch2:

Using 9 volt batteries, to power a cooling fan would be cost prohibitive!
You can get 9 to 12 volt DC wall-wart power supplies for very little cost, probably less than a cheap 9 volt battery would cost.

Thanks for the info, DieselJeep. What do you mean the CTC-25 is hard on flybacks? They run hot? All the more reason to install a fan I guess.

What I'd do is rectify the heater string (or feed it to a voltage doubler) to power the fan....It's less bulky, and comes on with the set, and I can make one out of the stuff in my junk box anytime.

Thanks, Electronic M. I'll ask Danny what he thinks of that idea. It certainly would be more convenient than having to plug in a wall wart every time I use the set.

For a fan get a muffin fan off an old piece of
test equiptment. Most run on 120 VAC & will move tons
of air. FBT's were common to melt then burn in these.

To move line trunk with blanket, put in face down. Make
it so the lid cant come down & hit the CRT. If you are
lucky & have a Roadmaster it may go all the way in especially
if the legs come off. Also pull knobs off.
A lot of sets came in & out this way & never lost a jug.

I have a LeSabre. The plan is to take the CRT out and put the cabinet sideways in the back seat. We tried the trunk - no chance of it fitting in there.

I remember Danny telling me that there was remote control version of the manual tuner in this TV. If that's the case, I wonder if it's possible to replace the manual tuner with a remote tuner? That would be sweet.

I'm going to pick this TV up tomorrow.

I got this TV from Danny today. I made a miscalculation when I thought it would fit in the back seat. That was not going to happen. So we had to improvise.

The insides.

That chassis looks super clean.

Yep, and it has phenomenal picture.

It sure does! I assume that's a screen shot after you got everything all put back together?

Congratulations on your new RCA Victor New Vista Color Console :thmbsp:. Danny really is a very awesome guy and the coolest guy I know.

Very Nice set. I had one in a combo years ago. It had a solid state audio output stage to drive the big speaker system.

Thanks everyone. I got the TV all snuggled into its new home along with my 1941 Philco 41-255, 1937 Zenith 5S127, and 1940 Zenith 8S563.

I just can't say it enough. This TV's picture is amazing. Super crisp and sharp with very strong colors.

Does it still have its original CRT? I don't know exactly how old your TV is, but if I had to guess, I would say at least 35-40+ years. (I knew someone in my home town in the '70s whose family had an RCA TV very similar to this one, which is why I am estimating yours is at least 40 years old.) If the set still has the original tube after all those years, it is truly amazing that you are getting such a great picture. My best guess, however, is that the tube was replaced at least once, as it is all but unheard of for a CRT, b&w or color, to produce this good a picture after 40-odd years, unless the set wasn't used much by its previous owners.

Even at that, forty-plus years with the original CRT and making a picture as good as yours is phenomenal. Most color CRTs have either become so dim after this length of time (if they produce any kind of raster or picture at all) as to require a brightener, or else the filaments in one or more electron guns have burned out. Again, I think your CTC25 is on its second CRT. If it isn't, I'll be very surprised.

I'll have to call Danny and confirm this, but I'm pretty sure the original tube was rebuilt in 1973 or thereabouts, and the rebuilt tube was graveyard dead when Danny gave it to me. It now has a Zenith tube from Danny's inventory with super strong emissions. The TV was made in 1966 for the 1967 model year. So it is 50 years old.

I forgot to mention, the CRT has no safety glass. Instead it was fitted with a steel band to protect against implosion.

I got a video of this TV up on Youtube. Here is the link.

I like the plate on your car. The sofa.

I had a new problem arise with the CTC-25 today. I turned it on, and seconds later I heard some strange clunks. After that, I was greeted with a raster that was completely distorted, shrinking and growing rapidly, and buzzy, pulsating audio. I got a picture, but soon thereafter, it started rolling and then it went back to normal.

Intermittent connection maybe? Glad it fixed itself though. Absolutely beautiful TV with an excellent picture!:thmbsp:

Thanks, SwizzyMan. I love that Westcott of yours! Talk about beautiful. You did a fantastic job restoring it.
