No, Dammitt, I think it'd look better at MINE !! (grin)

Wow. Diamond in the dust. :thmbsp:

Penthode 09-06-2012 08:05 PM

A very nice find. I like the cabinet.

This must be CTC-5 week.

miniman82 09-06-2012 08:11 PM

Trade ya for my Maple finished Wingate? Nice set!

joemama99 09-06-2012 08:11 PM

Where did you get that,being in Florida?

DaveWM 09-06-2012 09:19 PM

its going to be a while before I get to it, still in the back of my truck. I want to finish up on that GE roundie before I get into another set. Maybe in a couple weeks before I can get any more details on it. Between this one and the 2 other 5's I have (both are pretty ruff and I have not touched them so don't know much about them), I am pretty sure I will be able to get it going. My next oldest nice set is a CTC-9 with a good 21CYP22 so it would be nice to have something older. I like the sets with the doors on the front, nice protection for the CRT's.

tvtimeisfun 09-06-2012 10:11 PM

I like those round tube rcas
 
:banana::banana:Hey I had a ctc5 I sold earlier this year sometimes you have to let it go for something more important I did get a ctc 16 but the crt is broke hope I can find another crt for this set:tears::tears:

zenithfan1 09-06-2012 10:17 PM

Great score! That Wingate is very nice looking, where did you find it? My Wingate is on the NEVER sell list, they are just so pretty, it's the best 5 you can get IMHO:D I hope your 21AXP22 is good. It took me about 3 years to find a good one for mine but it was worth it to keep it un-modified.

Charlie 09-06-2012 10:46 PM

Awesome find!! I like that style cabinet! :yes:

I wonder if it migrated south with a retiring couple who may have bought it new. Wouldn't it be a gas to find it was purchased on Radio Row?

Dave,

Welcome to the Wingate club. Seems a lot of this model were sold and are turning up. It was RCA's most expensive CTC-5 model. I have the Maple finish but have also owned a Wingate in the French Walnut finish. Very nice find.

But I'z gots more rooms to puts it in so I's can finds the perfect spot.:D

hi_volt 09-07-2012 09:54 PM

I think it would look great displayed next to my CTC5 Chandler :banana:

mstaton 09-07-2012 11:02 PM

Would look even better next to my Stanwyck. :)

ctc17 09-08-2012 08:03 AM

:wtf: :worthless:

Sandy G 09-08-2012 08:34 AM

Well, I think it WOULDN'T have a hard time finding a new home if he ever decides he don't want it no more...(grin)

went ahead and pulled the chassis. do not see anything burned up, the PT has continuity, no B+ rail is NOT shorted, but one fuse was open (one of the two mounted on the top of the chassis.

DaveWM 09-16-2012 05:09 PM

tube sockets and pins show rust, hope the humidity will come out of the flyback. I have it inside now so hoping the AC will begin to dry it all out. Its going to be a while before I work on it but at least I have something t look at while hand heals up.

I still don't get how the CRT removes, it looks like there are 4 bolts on "fingers" that engage the plastic cover. I will re read the service manual when I get that far. The yoke plastic is disintegrating, but I think I have seen folks post on a fix for that.

Tom S 09-16-2012 05:37 PM

Beautiful set. Hope it works out to be a great playing one

DaveWM 09-16-2012 06:54 PM

I am tempted to pull the B+ fuse and see how the PT checks out...

snelson903 09-16-2012 06:56 PM

oh man you brought this post back up again ,i had forgoten all about it . now we got to start over again of who's house it would look the best in.

DaveWM 09-16-2012 07:19 PM

its going to need a bit of work, besides the busted CRT (guns looked perfect), no back, its also got some rot on the bottom of the feet maybe 3/4 inch. I am thinking either cutting off and grafting on some new back feet (the front is ok), or trying some of that epoxy fillers. Also missing the door pulls (I have the top but not the main door pulls). I was pretty pissed when I say the busted CRT but that's the way it goes sometimes....

DaveWM 09-16-2012 07:30 PM

did not have my metered variac handy I decided to throw caution to the wind and plugged it in. filaments came right up, B+ at the 5U4 cathode (fuse out) was 412vdc so so far so good. there are a bunch of paper caps so it would be pointless to go any further with out replacing those. I will check the filter caps, they are mostly single or two sections which is nice. I will take them out of the circuit and see how they check out for leakage, reforming them with the cap tester as I go.

your mistaken, it would lok beter at MINE! MINE! MINE!:D

DaveWM 09-16-2012 10:03 PM

pulled the chassis cover off the bottom of the chroma section (this one has that done point to point not PCB) yikes a bunch more wax paper caps. I can see this is going to take a while. One of my other unrestored 5's had a PCB for the chroma section. interesting that they are both considered 5's this is not a minor difference (at least in construction, maybe the circuits are the same).

there is a lot of wax film on on the PCB from the caps that must have oozed wax which then flowed all over the PCB. Normally I don't bother to clean them but these are so bad (wax film with dust captured) that I cant read anything. So I spent a little bit of time to clean up the boards.

DaveWM 09-17-2012 11:45 AM

well the 1st power filter cap was badly shorted, so I don't think I am going to waste any time on this. All the cans are very easy to get at with the bone saw so they will all get zipped off and caps installed from the top. using this process leaves all the orig lead dress undisturbed and is very very quick. 4 cans would prob take me no more than an hour to do if I get it all setup ahead of time (have all the caps on hand).

DaveWM 09-17-2012 01:43 PM

well I only have enough of the correct caps to do 2 cans, so I will be going over it and making up a list of caps for the whole set for order, then I can sit around and stare at it while recouping on the hand....

I should prob order enough to do all 3 of the CTC-5 chassis just to cut down on the shipping cost. would be nice to have 3 working chassis.

DaveWM 09-17-2012 07:09 PM

in my desperation to do something went ahead and cut the cans off and drilled the bottoms with my pin drill. Installed the caps in two of the cans.

DaveWM 09-17-2012 10:07 PM

while putzing with it I noticed what looked like a mod in the contrast circuit, a 68ohm resistor/cap tacked in between point "T" of the video board to the contrast, also the contrast pot has a 50uf cap and 1k resistor (like a cathode bypass setup). It would seem this is some kind of mod to the video amp tube cathode bypass.

mstaton 09-17-2012 11:44 PM

I did that mod to my 5 and made a huge difference. Before the mod, when the contrast was turned up, the HV would drop out and the picture would dim and blur. Link:http://i184.photobucket.com/albums/x...ontrastMod.jpg

ChrisW6ATV 09-18-2012 02:27 AM

I see this chassis still has its HV box cover. Very nice! It seems that nine out of ten CTC-5s have no cover.

DaveWM 09-18-2012 07:31 AM

that is the circuit, thanks for the link :thmbsp:

mstaton 09-18-2012 10:55 PM

I must be lucky, mine has all its covers.
