Wow, no telling what you find if you look around. I didnt notice that AK split off into a video area.
I didnt notice another area like the audio side has for this type question but I have a question about an old BW tv I just saw for sale/free.
Its an old RCA T-100, looks complete except the cloth is a bit freyed in one corner.
Im not a TV guy so much but I know there are some of you guys that breathe CRT's and really like the old stuff So I thougt if someone was interested I could direct you there. No cost.
In Seattle, Wa.

PM me.

Nuts. I'd take you up on that offer, but I'm oh so far away.

I got directions and will go there tomorrow morning. I need a T-100 like a hole in the head -- looks like the same TV as my 630TS in another cabinet. There's also supposed to be a Motorola combo (snore). Anyway, it may be fun to poke around. Sounds like these people owned a little bit of everything. I can earn some Husband Bonus Points by bringing along my sale-crazed wife.

Does it look like this?

Unknown RCA 10" ... picture1

I haven't seen the one at the sale, but here's what the tvhistory.tv website shows for a T-100.

Not bad, but it'd be a lot nicer is there was a 'c' in front of that 'T' ;)

Wish granted! :D

Went to the sale. The T-100 sits on a washing machine in the basement. Torn cloth, missing back, remainder not awful. Similar to 630TS, but not identical as I saw when looking at the chassis. Motorola combo in somewhat unusual cabinet with legs. Buried under packing materials, a plain Muntz b/w console with big honking CRT.

No great bargains or exciting treasures. They want $160 for the T-100, $150 or so for the Motorola, $100+ for the Muntz. They'll discount prices after 1:00 PM tomorrow. Not being in a buying mood, I gave them $2 for a pair of 1970s Archer rabbit ears and picked a Sony portable 5-307UW TV off a trashpile by the garage (just felt too sorry for it!).

The house had junk piled everywhere. The workers (and yesterday's shoppers) had torn through everything thoroughly. Maybe I'll go back around 3 PM tomorrow, but I suspect the T-100 still won't be cheap enough to tempt me.

Phil

Thanks for the photos. I'm surprised that they let people in the house like that. There was an estate sale here this morning. They took everything out of the house before the sale because they didn't think the house would be safe. Unfortunately no old tvs.

I'd have gone for the Sunbeam mixer in the first photo.

John

Wish granted! :D

:lmao: I thought you made that up. That's really on their website! :lmao:

jeyurkon, I have an extra mixmaster out in the shed. (got a whole collection) I could set you right up...

Man, that house is a disaster! But actually it looks a lot like the last estate sale I went to. Hard to sell much that way.

I think even if they cut prices in half I'd have to think hard before shelling out the money. The T-100 is pretty attractive to me but sounds like that one will need plenty of work; who knows about the crt.

Meanwhile, my free Sony from the garbage pile doesn't look too bad. Here's Obama on Face the Nation. They threw it out because it needs new caps in the vertical & horizontal. I just let the rain dry out overnight, didn't even brush off the pine needles.

To me, this is more fun than buying a set that someone else has already restored :)

Looks like my place :D

Plus, a model 9T246 shares that same cabinet style but with the KCS28(C) chassis. The only real way to tell of course is the label on the rear of the chassis.

'Fraid I'll have to keep my new $40 TV, torn cloth and all.

I made a deal with my better self. Dude, you can buy it if you promise to set it aside until you finish recapping that CTC-11.

Coupla missing tubes, coupla replacement caps underneath, nothing too scary. A mouse peed by the power xfmr but he was not a repeat offender. No, I will not just find a couple of replacement tubes and my variac . . . I will not, not, not!

I talked to the house owner, who was a child when the family bought the place in 1950. This TV dates from then. The back was with a pile of papers in the basement. Also the program from this guy's high school commencement. I guess he has kind of lost interest in the material world.

Despite the mess inside, it's a cool house in a desirable Seattle neighborhood near waterfront. Two blocks away is a little place for sale at $1 million; that lot has about the same square footage as my house.

Chassis KCS38. Anyone willing to scan a schematic? I promised not to work on it, but reading doesn't count :)

Phil Nelson

If you want a photocopy of the Riders info PM me your address.

Steve

Done. Thanks!

Phil

Looks not to be in really bad shape at all. My similar model, yes with the KCS28 chassis is awaiting my attention sitting in storage. Yea, a few other projects to wrap up before getting on that one and low priority at the moment.

I'd like to be able to find something that matches for that grillcloth.

Are you going to at least check the CRT?

I could test the CRT if I knew what type it is. No obvious markings, and I have no schematic.

Phil

It's a 10BP4. The service info is in the mail.

There is hope. The CRT looked flatlined on the tester but started to creep back after I cooked it with slightly increased filament voltage for a while. This may be my chance to try rejuvenation.

(And now I need to resume my real project as promised!)

Phil

This guy is a troublemaker but we're starting to make friends. Lots left to do! Thanks for the manual, Steve.

Phil

Probably more than you ever wanted to know about this particular set. Anyway, here you have it.

I don't see a good match for the grille cloth at my usual sources (AES or grillecloth.com). Any other ideas? It's not strongly patterned, but has little sparkly sprinkles.

Phil Nelson

Bravo http://www.jawaspot.com/smilies/clap.gif
That's an excellent write up of your restoration project and will be a great help for my 8T241.

I see we're using the same technique of restuffing - dremel, stuff, j.b. weld :)

I've been searching for 'sparkly' golden grille cloth for several months with no luck :( Some decent NOS/used stuff shows up on eBay now and then, but none so far with sparkles or metallic threads.

Bob

How about the spray glitter that women use in their hair? I seem to remember reading about someone doing that.

John

Great write-up :thmbsp:

That is funny about the color, but P-4 phosphor is actually a mix of a "yellow" phosphor which peaks at about 550 nanometers and a "blue" phosphor which peaks at about 450 nanometers... it appears that the blue "ages" faster than the yellow under years of electron bombardment.
Cool observation!

jr

The mix of phosphors sounds plausible. You would never notice something like this if you kept the same CRT in one TV for years, or put it in another TV with the same orientation. I know this CRT had a different orientation in its first TV because I had put a little lick of tape on the edge to show me where the top was.

Re cloth, years ago I made a sparkly replacement cloth for a Truetone radio by finding light cloth with the right texture, dying it with tea, and spraying it with glitter from a craft store. I followed that with a very light coat of satin acrylic to help the glitter stay on. It wasn't exactly like the original, but close enough that only another Truetone owner would have raised an eyebrow.

This cloth is huge by comparison. The glitter is actually sparkly threads that wander through the fabric in a vague wavy pattern. Maybe somewhere there is a costume fabric that looks close . . . .

I was going to ask about that. I've seen some screenshots of vintage sets here on the site & it seemed to me that many had a "sepia" coloration on the CRT. Didn't know if that was really the case(most late '50s & up B&W sets look "blue-ish" to me in screen captures). I thought maybe it was a setting on the digital camera used for the shot, but was never sure. Actually, I think the "sepia" effect looks better than the "blue-ish" one usually seen. Just curious about that, never gave a thought about the original phosphor colors of early CRTs,

The other thing that can happen is that the glass can "brown" due to soft X-rays from the beam. Picture 1 shows a 16AP4 (which was operated at about 15 kV) with a brown area where the tube has been scanned. I had to enhance the colors on the photo to get this very slight "browning" to show up. If I can dig out my 3NP4 projection tube (25-30kV), I will post it later.

Well, the browning on the 16AP4 looks real, all right. This TV makes only about 9KV, so presumbly X-rays would be less of a factor, but who knows.

Re colors in screen shots, I've found it practically impossible to take a photo that truly represents the picture. Different cameras make all kinds of color corrections (or "mistakes"), the most common being that a B/W screen will look too blue.

I haven't noticed this kind of effect before. Perhaps it isn't common at all.

When my old TVs are working right, the screens look black and white to my eyes, not brownish or bluish. If you look at the screen shots of Wallace & Gromit near the end of the article that I referenced, that is what this CRT looks like now. Those shots were taken in a dimly lit room, with the camera zoomed in so that it didn't "see" the room background and make color corrections for that.
