View Full Version : Going to pick up a CTC-12 tomorrow
freakaftr8 06-26-2012, 12:13 AM The guy powered it up. Yikes. Oh well to say the least it's been sitting in the same spot for 40 years apparantly untouched. But he said it worked. So guess that blows the variac mystery. It's an awesome cabinet with sliding tambour doors and a remote set too. 2 remotes hang off the back apparently.
This should be a cool set. Now if I can just get a CRT for my CTC-9.
I'll take some pics when I get it home.
It will be nice to tackle one of these considering all I have been doing for the past few years has been repairing plasmas. :banana:
mstaton 06-26-2012, 12:24 AM Sounds Awesome!. Plasma's can be nightmares sometimes. Especially those pesky Y and Z sus boards.
freakaftr8 06-26-2012, 12:37 AM I envision Sanyo ipm modules dancing in my head. Lol
zenithfan1 06-26-2012, 12:39 AM Awesome! Looking forward to seeing it. Great score Shawn!
mstaton 06-26-2012, 12:41 AM I envision Sanyo ipm modules dancing in my head. Lol
Yeah, I had my fun with those! I thinlk they are mostly all LG sourced.
freakaftr8 06-26-2012, 01:19 AM Thanks mark! Looking forward to it. And yes those ipm modules suck getting
Off the board. When there bad I just pry 'em off. Lol
DavGoodlin 06-26-2012, 07:45 AM and a remote set too. 2 remotes hang off the back apparently.
Congratulations on another roundie saved! :yes:I cannot wait to see it either. It seems like RCA sold the more interesting models in California.:drool:
PM me down the road if you need factory info on the remote chassis CTPxx, I'm not going anywhere.
freakaftr8 06-28-2012, 10:40 AM Well I picked it up!
Before I even unloaded it from the truck I removed the back to make sure no critters were living in it, and to my surprise what do I see?
Well no critters, but it's a CTC-10! But it has a 21FJP22 with a CRT brightner on it...
Boohoo. Well guess it's time to break out the tester..
The remote is really cool! It has adjustments for color, tint, channel, on-off and volume.
freakaftr8 06-28-2012, 10:46 AM Even better news... The red screen control is cranked to the max. Blue and green are at 3/4.
edit: btw, the CRT is a noname labeled 21FJP22 Rare Earth. Looks to be very clean, while the rest of the chassis is barely dusty. Not a smoker set. Very clean inside and out. I went ahead and powered it up with the usual checks, Hout pulled, so I replaced the tube, crossed my fingers and vioola.. Picture!
Dim.. very dim...:tears:
freakaftr8 06-28-2012, 12:15 PM Oddly enough, I cannot find the cabinet on Ed Reitans site for the CTC10.
http://novia.net/~ereitan/Gallery/CTC10_Gallery.html
The closest it comes to is the Wynnewood. Ill post some pics of the cabinet and the TV later today. Oh and this set if full of replacement Realistic *Lifetime* tubes.
DaveWM 06-28-2012, 12:22 PM are the G1s all tan looking? or worse Blued?
freakaftr8 06-28-2012, 12:46 PM I cannot tell. The bakelite base is cracked and the brightner does not want to come off. Its going to break. :sigh:
are the G1s all tan looking? or worse Blued?
miniman82 06-28-2012, 01:37 PM are the G1s all tan looking? or worse Blued?
Just curious if that's an indication of anything? They heat the gun structure during the evacuation process, and G1 goes from shiny silvery metal to pale gold. Just saw it happen on my own tube today right before my eyes, brand new tube.
DaveWM 06-28-2012, 02:04 PM hmmm thats odd, most of my roundies with good tubes are silver looking G1 not so good have a dull tan, ones that got brightners are blued.
DaveWM 06-28-2012, 02:06 PM I cannot tell. The bakelite base is cracked and the brightner does not want to come off. Its going to break. :sigh:
You should be able to see it, its the 1st round elements in the neck coming from the base side. I am assuming that is the G1
I would shoot some loosen juice on it, the focus pin is prob corroded.
Sandy G 06-28-2012, 02:07 PM PUH-LEEZE Be Careful !!
freakaftr8 06-28-2012, 05:02 PM Ok. They are pale gold.
zenithfan1 06-28-2012, 06:29 PM :worthless
miniman82 06-28-2012, 07:53 PM hmmm thats odd, most of my roundies with good tubes are silver looking G1 not so good have a dull tan, ones that got brightners are blued.
Perhaps the ones that are still shiny didn't have the guns completely bombarded? They turn each element cherry red, to shake the air molecules off of it.
ctc17 06-28-2012, 08:49 PM There maybe something to that G1 color thing. I have noticed it but never paid close attention to .
I wonder if its where the filament evaporation deposits. Much like how a non gas filled light bulb gets that silvery gray coating on the inside from the boiled off tungsten.
miniman82 06-28-2012, 09:43 PM No, that stuff typically ends up in the neck near the base. The 21AXP22 in my Sylvania set has that going on, same way as an old light bulb. I guess it actually is an old bulb of light, depending on how you choose to look at it.
marty59 06-28-2012, 10:34 PM The bakelite base is cracked and the brightner does not want to come off. Its going to break. :sigh:
You can also gently pry between the two with a couple of small blade screwdrivers opposite of each other or if you have to hold on to the (loose) base then work your way around and just pry a little at a time.
freakaftr8 06-29-2012, 09:17 AM Hey all. Here are some pics..
Sorry for the pic delay..

old_tv_nut 06-29-2012, 09:25 AM Very dignified cabinet - could fit in the library of a mansion or I could picture the President watching it at the White House. :thmbsp:
DaveWM 06-29-2012, 09:30 AM has the cool color hologram badge as well.
Sandy G 06-29-2012, 10:11 AM Me Likey ! There's just "Something" about a Roundie, especially a hi-end one like this...They're SO "Elegant" & "Sophisticated"...A set like this would about always be in the "Company" room, where the kids, dogs, food, etc. was NOT allowed to go... Mom would be in her Sunday best, Dad would have his jacket on....Always CLEAN & NEAT in that room...If you lived back in that era, like I did, you know what I'm talkin' about.
consoleguy67 06-29-2012, 10:26 AM Beautiful cabinet! What year is that set from?
DaveWM 06-29-2012, 10:37 AM yep that room was strickly off limits to kids, adults only.
DavGoodlin 06-29-2012, 11:05 AM Really sweet! Never did see a CTC10 that high-end! Is there a safety window that was removed?
Phil Nelson 06-29-2012, 11:13 AM If it is like my CTC-11s, they came with the safety glass or without.
Phil Nelson
freakaftr8 06-29-2012, 12:13 PM Right. No way a safety glass was on this set. It was built
Without. Oddly enough I cannot seem to find this puppy on the CTC-10 catalog. Possible rarity here? Oh and what was the original CRT? The tune diagram in the cabinet someone markered over the tube type. Not a cyp nause of the bonded safety glass.
mstaton 06-29-2012, 01:36 PM 21fjp22
zenithfan1 06-29-2012, 02:01 PM Beautiful! I've never seen that cabinet before either, not in brochures or in real life. That is one hell of a find!
freakaftr8 06-29-2012, 02:07 PM Components in the tv date February 1961.
Beautiful cabinet! What year is that set from?
zenithfan1 06-29-2012, 02:13 PM Late CTC10, must have been RIGHT before the 11. I'm still drooling BTW :D
freakaftr8 06-29-2012, 04:39 PM Here is a pic of how the CRT looks and this is really cool too!

Henredon fine furniture. That company is still around too!
Sandy G 06-29-2012, 05:05 PM Yeah, Henredon's Top-Flight stuff. That was a BUX-UP set when new...Did you go over it w/Pledge or something, or is it just THAT Purdy ?!? (grin)
zenithfan1 06-29-2012, 05:15 PM Did you get the brightener to come off? If so, it looks like there's life in that CRT.
freakaftr8 06-29-2012, 05:19 PM Nope it was just meticulously taken care of by the original owner.
The CRT brightness still on it. I figure let er cook at 8 or 9v for a few more hours then I'll get it off and check the CRT.
zenithfan1 06-29-2012, 05:21 PM The heat may help loosen it too, you said it was stuck on there pretty good. Good luck with it, I hope nothing breaks.
freakaftr8 06-29-2012, 06:40 PM Well red green and blue all well into the bad range.
zenithfan1 06-29-2012, 07:03 PM Give 'er a whack with a tester, what tester do you have? I've had amazing results with a Sencore CR-70.
freakaftr8 06-29-2012, 07:48 PM Semcore cr-161.
And. Yep I did. I let the CRT cook overnight so I figured what to I got to lose.
And the results were.
Red. 1/4 in the good
Green just barely good
Blue half in the ?
So I plugged it back in did a quick convergence and purity alignment with moderately impressive results. Then....
It started to look hazy and dim in the blue. Then a little darker.
So I tested the guns again and all but red were in the bad again.
Red was in the ?
So I started running it with the juice bumper again and it looks a whole lot better. Sadly I think this CRT has seen brighter days.
bgk283 06-29-2012, 07:55 PM wow, thats nice, have fun with that.
miniman82 07-01-2012, 09:47 AM Sounds like the tube is gassy, the cathodes are becoming contaminated. Time for a replacement.
mstaton 07-01-2012, 01:46 PM Just go down to local electronics store and order one. LOL Someone here should have one.
freakaftr8 07-01-2012, 09:45 PM I wish. Looking for one. Anyone??
freakaftr8 07-02-2012, 09:28 AM Yesterday morning my 3 year old and I watched the jungle book on the 11. About near the end of the movie the CRT got dimmer and dimmer and blurry.
So.. I gave this tube one last bump before I gave up and looking for a replacement. I left the tube cooking for at least 6 hours at 8.5v so it got nice and hot. Dialed it back to 6.3. Checked emission. All 3 barely registered. So.... I wacked all three guns at rejuv 3 function. What a spark, very audible!
Results were impressive. That's what's wrong. I had a smear issue I was trying to chase down in the IF section. It was the CRT that was causing all the issues. Well nice and bright now! Lol doubt it will last a day like this. Actually the chassis outputs an excellent image. Oh and the filters measure good. But I'm monitoring them.
freakaftr8 07-02-2012, 03:04 PM Anyone else had results after rejuvenation that lasted?
DavGoodlin 07-02-2012, 03:26 PM Yes, Zenith 25VBQP22 (1973 25DC57) looked good for another 12 years after a serious blast. I think the key may be that you need to use it regularly once you do it.
miniman82 07-02-2012, 08:02 PM If it's a cathode contamination issue (gas), you'll have to whack it now and again because the gas will just redeposit and poison the cathodes when the tube is not in use. Best thing is just to replace it.
freakaftr8 07-02-2012, 10:23 PM Sounds like why my wife does to me when I make her mad. Lol. I'll keep an eye on the CRT emission level this week and see what happens. Meantime I'm going to test tubes and check some circuits in the vertical section. The linarity is off and seems that I went through this with my ctc-16
ChrisW6ATV 07-03-2012, 11:24 PM Anyone else had results after rejuvenation that lasted?
With black-and-white CRTs in commercial use, I have had some rejuvenated tubes last for years and others die within weeks, so no consistent results here. All of these were in use 24 hours per day before and after rejuvenation.
Tom S 07-04-2012, 12:49 PM I usually use a clean and balance setting on my Sencore Big Mack. Full restore as a last resort. I checked both of my sets. One having a CYP and the other an FBP. CYP is great and I left it alone. FBP has a cateract that I want gone and emission was just a tad low. Cleaned and balanced it end of April. Checked it end of June and it's great but I use it regularly. I am going to look for an extra CRT just to have one. I love these old sets and thank got for ME TV. Really takes me back.
