Great little rescue from TV massacre

[YamahaFreak]

(Apologies in advance for rotated images and multiple image posts; my old iPhone is very limited in what it can do while posting.)

While returning an application to the local thrift store, I made a horrifying discovery: apparently, once their floor/shelf space dedicated to TVs is full, all sets donated after this point go straight into the compactor. I didn't want to risk looking at the pile and being heartbroken, but in the end, I'm glad I did. Amongst 30-plus late-model CRTs in the 'TV Holocaust' I spied a tan and brown cabinet with a luggage handle and integrated rabbit ears, and immediately thought I had found a tubed set. I grabbed the little guy and rushed home, eager to analyze my rescue. What I found is a 1978(?) Admiral KMC13-100 solid state knob-tuner color portable. Aside from his AC cord having been cut and one of his antennae tips being snapped off, he's in good shape, and very lucky I came along! I wired on a new cord and the set works, but has vertical roll until warming up for about 30 minutes. (I can't find a vertical hold control anywhere inside) As I understand, this TV, along with a contemporary 19" model, were sold exclusively through Kmart stores. Once it warms up, the color is very rich. I actually really love the picture!

The Admiral right after I got it home. Note the 'X of death' that is scrawled across the CRT of all sets destined for the trash.

First power-up with a source

Here's a view of the chassis.

Finally, the picture after a bit of tweaking. Sorry again for all these posts!

Thaty sort of reminds me of the "cash for CLUKNERS" fiasco...where peole were FOOLED...into thinking they could get 4k for a "clunker" (often a PERFECTLY good used car.)--to trade up on en "efficient model". Thise poor cars got a similar fate...and had a similar mark on them or the word "clunker" written on the windshield..

One of the biggest screwing since removing freon from inhalers.
I was looking for a winter car & the Ford joint had a few Crown
Vics clean & under 100K. Couldnt sell them. That damn program
cost poor folk dearly by taking good low priced cars off the market.
Those poor CV's still had 10-20 years of life left.
And if you do the math it cost us over $50,000 per rebate.
Same with TV. How much did converter boxes cost us? Disposal ?
Energy & pollution to build 90% unneeded sets. Forced cable &
satellite due to going from over 20 OTA on rabbit ears to one
intermitant station ? Thanks for not minding your business.

Trust government to do the right thing ? ASK AN INDIAN.

I talked to a mechanic at a dealership and he referred to CFC as one of the bigger scams ever. All they did was jack up the price of the cars another 4 grand. People were too stupid to know that they were being had.
And some fools are going with 84 month car notes. They're upside-down on the deal in 3 years.

Wow, that thing's clean, nice catch. Never saw the Solarcolor name on a portable before.

I'm glad you were able to get that set without them stopping you (some of these places get real bitchy over people picking stuff out of the trash pile).

Some new electrolytic capacitors in the vertical oscillator circuit should take care of the rolling.

Admiral is a brand that I've never found much of in my area and I think yours is one of the last ones (I think the last American Admiral TV plant was closed in '79).

The big 'X' on the CRT was drawn with a black Crayola, I think. It's the same tool they use to write their prices on stuff. Comes off easily with a dry rag, but persists if you use a wet one.

Ditto the sentiments about C4C. One of the single most wasteful government 'programs' I've witnessed in my time on Earth. I was lucky to have not witnessed too many vehicles destroyed.

This set has a Japanese picture tube, but I don't believe it's an AOC. The back panel states it was made by Rockwell International. The other thing I noticed is the power cord appeared to have been cut long before the thrift stote got it. They may have never powered it on for test, and tossed it aside as soon as they saw knobs. Must be a dirty word in thrift stores these days. :P The only other sort of issue is the picture is moved considerably to the right, with the right-most edge cut off a bit. I wasn't able to locate a horizontal control, other than a horizontal lock, which did move the picture but caused it to go haywire if I tried to move the image to the center.

Your set is according to Sams a M46 chassis. Sams 1814-1.

The horz & vert is a count down circuit. IC600 is sync sep & a
divide by for H&V osc. The 'lytics that are in the circuit are
C801 1mfd
C806 1mfd
C807 33mfd
One of them probably is causing both problems.
25V caps are way fine but what the hell use 50's !

VCC for the IC is pin 11 at 9.3 VDC
There is a start & run source, more on that if necessary.

I will keep out the Sams if you need more.

need to tell these Thrift Store workers that any set that says "Made in USA (or America)" is a collector's item and is valuable since they don't make anything in America anymore. They represent a bygone era and those manufacturing jobs are never coming back.

Look at the HV capacitors that connect between the collector of the horizontal output transistor and ground. It's possible that one of these has either driften in value or opened. These can also have an effect on the HV; so, be careful and replace them with the same rating as was originally installed.
