Kutztown finds
 
1 Attachment(s)
Got there at 8am. Went thru the whole place. Saw a zenith I was interested in. Negotiated with the guy and got it :banana:. I think it's a 5-S-127. All original.
I've been looking for a black face zenith for awhile. Paid a little too much for my taste, but knew it would not last long. I did not see another one like it there. Going back tomorrow to see what else I can find.

Found this nice GE radio at a Goodwill in indy recently. It has a 6L6 amp !! Cold chassis and an 8" coil-type speaker. Not in bad shape--and CERTAINLY worth $14.00 plus gas money to go get it !!

What model is it?
Did someone put a 6L6 instead of a 6F6 or so? :scratch2:

rca2000 05-08-2015 09:02 PM
A GE E_81

No--it is SUPPOSED to use a 6L6 amp tube. It is in riders 7 I think.
It also looks like someone has replaced the caps with newer ones underneath--the pix shows the pair of them missing along with the rect. tube. Hope that big power tranny is ok...

I have NOT picked it up yet. Was doing so today--and got in a traffic jam which messed things up for me BUT. I AM getting it Monday--i want it before my radio club Tuesday night for "show and tell".

stusnyder 05-08-2015 09:25 PM
Just pulled this chassis out of the zenith. Looks like it was never touched. Riders show 2 lytics c16 16mfd c19 12mfd. On mine, c19 is stamped 40mfd :scratch2: So what value do I replace it with?

rca2000 05-08-2015 09:34 PM
Not totally sure I would want to replace a 16Mf with a 40 MF on a vintage radio. More like a 22Mf one. Perhaps a 40MF might be ok--but then again...it might stress the rect tube. For the 12Mf one--use 22MF one.

Just make SURE--you do not go below the B= voltage--even WITHOUT a load. But do not go too much ABOVE the rating either. For example. If it is a 16/250...do NOT put in a 16/450. a 350 would be ok. It is hard to explain--but if the voltage is too LOW...the cap will "deform" and rapidly get high ESR. I have SEEN this before.

stusnyder 05-08-2015 09:50 PM
Yea it just struck me weird that riders said it's suppose to be a 12mfd and the actual one in it is a 40mfd. And there is no evidence it was ever changed.
I just might hook up my heath cap tester and see what that comes up with...although I got a feeling it's most likely dead.

Reece 05-09-2015 09:35 AM
I was at Kutztown for about an hour Friday, got there about 8:30. Lots and lots of interesting stuff, as usual. I looked in particular at an RCA and a Stewart Warner console but passed on both for various reasons. Getting picky in my old age.

I was kinda trying to keep a eye out for you, but missed you. Friday was cathedral day. Saw so many of them.
Went back today, and what a disappointment today was. Alot of venders were gone, and alot were packing up early. I bought some caps and on the way out, I grabbed a nice norelco tabletop in Bakelite for 20 bucks.

Oh, hey! I just noticed your location tag. Hello from over in Myerstown! :wave:

You should have stuck around, the club table had a load of cool stuff at it still when dollar time began. Even when it became "Distributed Garbage Removal Time! Please, just take it away!" there were still useful things to be had, both small and large. I mostly loaded up on the small freebies this time around, on top of the $24 worth of dollar time purchases I had already schlepped over to the car...

Today could have been worse. It didn't rain, it wasn't unbearably humid, and the temperature was nice up until about 90 minutes before the dealer raffle drawing.


I'll post a more comprehensive list with photos later on, but I came home with two medium tube caddies; one Sylvania in "fair" aesthetic condition, solid mechanical condition, and one Zenith in very good condition all around. In the same theme I picked up a Zenith serviceman's caddy (Designed for the solid state era inside, by the looks of things.) in excellent condition. Finally found an AM/FM Bakelite cabinet radio in straight forward restoration condition, which also happens to be Zenith, and then I took pity on the B&W Zenith portable (1981 vintage) that was still at the club table. Zenith turned out to be my theme today. I also grabbed another Riders TV manual, Volume 8 this time,(If I get one volume every Kutztown, assuming no duplicates I'll have more than half of a complete set by 2020 I think.) and one of the "3 neons and a meter" style B&K CRT testers in unknown internal condition. I'll dig that out tomorrow and figure out if its worth overhauling or not. (Dollar Time score.)

Were there many TVs at the meet?

I saw no less than 10 pilot TVs, a guy who had a Siesta and a Princess both with known working CRTs, and between the two you could have one very good condition visually, and one "acceptable but battle-worn" visual condition. A few bug-eyes and portholes several space-command sets, some motorola electrostatics. Didn't see any color roundies, but then again there may have been some Thursday or Friday.


Anybody know what happened to the very large, very heavy, all metal cabinet RCA that I spotted perched on the dumpster out by the front lot around 12:30 on Saturday?


Edit: TV Parts everywhere, yokes, vert-block-osc xformers, brighteners, a few flybacks, etc.

stusnyder 05-10-2015 07:15 AM
I left about 1:30, and that rca was still sitting on the dumpster.
At that time nothing on the club table really interested me.

Reece 05-10-2015 12:02 PM
Hello, Myerstown from Cleona! I'll be back up there in September.

Did you check the ratings label?
If the power transformer is a little larger, it might be a 25 cycle set.
Might be from the area where 25 cycle was common.

I looked up the Riders and it does use a 6L6.
Rather impressive for a GE. Also, a high tube count. Great find. :thmbsp:

stusnyder 05-10-2015 08:27 PM
Well turns out the power tranny is toast. I suspected something when I pulled out the chassis and there was melted wax on the bottom of the cabinet and the dial lights were dim after recap. Trans got real hot real quick, even with the rectifier tube out.
I checked over at arf and found a posting about these trans. They said to use a trans from AES part number p-t27bx. So I ordered one.
Now I got a question. According to the riders schematic pin 4 and 6 on the 5y3 are suppose to have 305 volts ac on them. The schematic on the transformer I ordered has 600vct on the primary not counting the center tap.
Do I hook it up the same even though the voltage is higher?

rca2000 05-10-2015 09:03 PM
That probably means 305 volts AC to GROUND....on EACH pin--and it would be about 600 v. ac between them. so--that tranny sounds just about right.

rca2000 05-10-2015 09:04 PM
The rect. tube looks to be missing on that GE..I PRAY...that big tranny is not gone on it !!

So then the center tap goes to the c19 12mfd lytic like the original trans did?

HI NoPegs, that 1981 BW Zenith was my donation, working when I brought it.
Came from an estate in Lancaster about 12 years ago along with a 1949 Emerson 544, 1960 Emerson 23" and 1970 Philco 9" B310W.
The owner was a never-married nurse at nearby Community Hospital. Her entire TV ownership history and everything else was there.

I did see an RCA CTC9 "Abbott" with legs included, that sold pretty quickly for $200. Same ex-tv repair guys from Philly that sold me a working Sencore VA-48 for $5 one year. I suspect he may have more treasures in September.

Well, at least you can rest easy knowing it went to a (mostly) respectable home, and now I know the back-story on it. Focus is a bit soft, but I don't think that its the tube's fault. I think it just needs adjusted and maybe a few electrolytics replaced on an as needed/probable cause basis. I believe it is destined to become the workbench TV. Big enough to watch, but small enough to find a place for it to live permanently.

The center tap goes to the same place, the original transformer CT went.The set uses a B- line to provide bias for the audio output tube.
I have to look at the schematic again. :scratch2:

Ok then there is 2 taps left, 5 volts and 6.3 volts. I assume the 5 volts are for the dial lights, and the 6.3 is for the filaments, correct?

Reece 05-12-2015 05:56 AM
5 volts is for the rectifier filaments. 6.3 is for other tube heaters and dial lights.

It seems that the 6.3 volt heater winding is a little skimpy. Only 3 amps!
The tube count shows a load of 3.45 amps, including the dial lights.
You'd have to check the operating temp of the PT, after a few hours. If it seems to run warm, you might have to subsitute #47 dial lights to reduce to current a bit.
Depends how much reserve is built in the transformer. Hammond transformers are a great product! :thmbsp:

I got the transformer on monday and Installed it. I also fused both leads on the secondary that go to the rectifier. After about a hour running it started to get warm. I pulled out the dial lights and they were 44's. I put in 47's in. I'll have to run it tomorrow night to see if anything changes heat wise on the transformer.
What a sensitive radio! Especially on shortwave. Got all kinds of stations, more than any of my other radio's :thmbsp:

I recommend not to substitute 350-450V capacitors for 150V ones on any AC-DC chassis. The so-called "universal" power supply uses a half-wave rectifier, and the 150V capacitors were designed to live with the ripple current. 450V capacitors were designed to work with full wave rectifiers and simply couldn´t cope with the half-wave ripple, so they failed miserably pretty soon. And one was left wondering why.

So you're from Myerstown, PA Huh? That's funny because I have some relatives that live over there, in fact my great-grandfather owned the Chrysler Dealership that was there for many years! :yes:

Well, my data-plate reads: "Assembled and Tested in Bloomsburg, Pennsylvania." But I've called Myerstown my home now for the last 8 years. :thmbsp: Small world indeed!

Speaking of Kutztown, I'm planning to go to the fall one in September. First time there :)

Should I start looking into getting a hotel now, or do I have time?

ekimetsok 07-17-2015 08:44 AM
Why bother with a motel? On-site Kutztown kamping is free. Not unusual to see everything from pup tents to Class A motorhomes. Renningers has pay showers too.

Kamakiri 07-17-2015 09:55 AM
Maybe in my 20s, but when I hit 40 my body decided it liked nice cushy beds. Preferably at places with a free continental breakfast :D

Electronic M 07-17-2015 11:23 PM
I've been entertaining the idea of driving to the fall one and camping in my Lincoln...

Start looking now! I'm going to try and make it multiple days this time around. I want to experience the bonfire for once! (With the YL along too!)

Kamakiri 07-18-2015 06:12 AM
Does anyone have reservations at any place yet?
