Hey, I finally want to see about getting to this TV of mine.
Some of you may remember that it is the one a stupid 16 y.o. came on here about, complaining that the picture went out of whack after 5-6 minutes. :roll: Back then, I knew nothing of the deterieration of caps and other misc select parts over a 50 year period.
Anyways I was wondering where I may find a schematic for it at. I'd prefer not to buy one if not necessary. Then I can see about compiling a parts list and get to it after a few more radios that I have on my list before it.
As usual thanks in advance for any help.

Just wanted to say that it's a pretty cool set you have there! I just got into these metal late '50's sets myself. They play so well when restored.
Good luck with getting it going.
I think this was the set used on "Laverne and Shirley" and in the boys bedroom on the "Brady Bunch" - just a little useless trivia! :D

Schematic is in Sams set 396, folder 3 which I do have. PM me.

Thanks, It actually did look pretty good when going. It just always lost its Horozontal hold(?) The picture would break up.
Ive never actually warched L&S and I havn't watched the Brady Bunch for a few years but thats cool. I did not know that.

Ya-know, I also have a 1957 GE 14" portable too that I got working with a little fiddling, unfortunatly it needs more work now due to being in a flood. Whats more unfortunate about that one is that its a rare model with an alarm clock on the top. You could actually set that TV to turn on at a specific time!
Hey let me know how yours go too for ya!


mr_ed01- I sent ya a pm.

Nice set.
If you want to PM me the KCS number, I may end up with a spare OEM svc manual for that during the storage area cleanup.
Yours for the postage if one surfaces. (Otherwise its headed for the recycling center like I did with 100+ lbs of RCA OEM duplicates & Goldenrods & 500+ lbs of Sam's already.)

Chassis should be a KCS111D. That number should be located on the back of the cabinet or chassis.

Sent ya a pm Frank.


Thanks Kevin, for cluing me in on that. I didn't relize it was another number for the sets identification. Specifically Chassis ID.
Anyways that number is KCS111DRVA274, under that is 7425L1A. I dont know if that ones related to the kcs or not.

Anyways when i had it open i also noticed this nice burn

Anything I should really worry about with it?

It's not really a burn, it's a rotted yoke cover, very common on sets of that era.
It's worse in the one spot because the heat of the tube next to it accelerated the deterioration.
Nothing to worry about as long as the cover still holds the yoke in place.

Ok, I finally got to thinking about getting this project moving again. :roll:
Got some others done, but I still have 1 radio I want to recap and troublshoot beforehand, but for now i've started my parts list. I've got all the caps listed but was wondering, for when I make an order, What voltage should they be rated for? The schematic only lists a few of the caps voltages, and those ones are real high. Same questions go for resister too, when needed.

umm,... any help? Would standard 630 volt work? Do I need higher, or would they be lower value??? I'd like to order a large cap kit, that I know will cover this set.

What type of schematic are you using? Do you have a Sams for that set? If so, the parts list will give a list of off caps, and your paper caps will have replacement voltages. Normally for paper caps, I always use 630V unless otherwise states on the schematic or parts list.

The Schematic, I believe is a Sams (not in hand right now) but there's no parts list. I have to make one off the schematic diagrams myself! :? The schematic only has a few voltage ratings for some specific caps. The rest is blank other than capatanance rating. If 630v is good for the general bunch, other than those few i'll pick a lot up.

Sams 396-3 should include 18 pages, including a parts list.

As mentioned above, the Sams, if it is complete, will have a parts list. Also, the capacitors in the set are almost always marked with both the value and the voltage rating. For the wax paper caps you may have to scrape off or melt off some of the wax to read the ratings. For bumble bee caps (which are wax paper inside) there are web sites that tell you how to read the stripes. It is always a good idea to check what is actually in the set as Sams sometimes makes mistakes and sometimes there are production changes not shown in the Sams.

Most caps are rated at 600 volts or less. Occasionally there will be a 1000 volt cap. It never hurts to use a higher voltage rating cap, so use 600 volt caps everywhere unless replacing a 1000 volt cap.

For electrolytic caps you can also use a higher voltage rating and you can also use a higher value. 50% larger is OK. For paper caps you need to use the original value. Using a .047 in place of a .05 is OK and you may have to.

:? Mine don't. I only have 13 pages. 3 of the main schematic, a few alternate of the tuners, some pictures pointing out the parts on the pc board, and chassis behind the picture tube and a few on alignments.

Hey Tom,
I know the caps are usually marked themselves but im not taking this baby apart until the radio I have in peices is done. I just wanted to beable to stock up on the majority of the caps before I break into it. Ive also got the bumble bee codes written down,... some where :roll:

Ok, I just didn't know if they were all going to be higher because this will be my first TV and ive only worked in the radios so far which dont normally use as high of voltages.
I allready knew the jist though, of the general rules of replacement cap values. :P

If you pm me what pages are missing(they should have page numbers) I can scan any missing pages for you. I'll need your email too.

Hey. that would be sweet! :o Thanks, i'll PM ya when I get my crappy laptop (with the pages on it) back a little later tonight.
Sucks though that I wasted 3 hours making a list of 313? capacitors/values. :x

You don't want to replace all the capacitors, only the paper ones from .001Mf and up, maybe 25-30 of them .
Changing Ceramics and Micas on a set of that vintage is a waste of time and money, plus it'll likely not work right afterwards without a full alignment.

Those sets have a metal shield covering the bottom of the PC board, it needs to be unsoldered so you can replace the capacitors. It's soldered to the PC board in a few spots so you have to be very careful unsoldering it so you don't damage the traces on the board.

I just got done recapping the 17" version of this set so here's a couple pictures of the shield, you can see one of the tabs that solders to the board.

Yea, I know, I just wanted to have them all listed. Then I would mark that list off as of which ones were to be replaced, and which weren't, and to have the list up close on paper while i'm looking at the labeled photo's of the chassis, that the schematic has on the pc.
