By luck, I ended up meeting a guy that has many many tube radios and a few tube tv's.

I bought one tv set from him, and the ENTIRE "Sams" collection up to 1970. I paid 100.00 for the TV Set, and 50.00 for the Sams.

The Sams was basically an entire pick-up truck load... Hopefully I'll never need to search for a schematic again!

The TV set needs a recap. I know, I'm not supposed to plug it in, but I did anyway....

The set works like it was brand new.

See the attached picture, keep in mind i'm running an old vhs tape through a very old VCR as a signal source....

The cabinet is in very very good shape, I didn't even clean it up before I took this picture.

Inside the set was a tag from a picture tube replacement in 1970.

Well this morning I decided to unload the 1000 pounds of Sams binders out of my truck and find the Sams for this set. I found it and whimpered a little bit when I saw how many capacitors this thing has.... I know, it's all part of the hobby but I wasn't ready for that.

I think I'll start with the Filter caps and see how it goes from there.

I hooked the set up to my Sat TV box last night, the picture is absolutely amazing!
I really did luck out with this set.

Looks like a really nice set - congratulations!

Congrats on the SAMS score too!

Maybe some of those caps got changed in the 60s or 70s? If they put a crt in it that late then they kept it well maintained for a long time. Seeing this makes me want a DuMont-I've never found a "real" one. A friend of mine mentioned finding one in an attic somewhere but I guess he never followed up on it for me.

The guy that I bought the set from used to be a technician back in the day. He replaced the tube in 70, and I have proof. I found the warranty card with his name on it inside the set.

But I was looking at some of the cans. The are metal with "Sprague" labels on them. They just look different.

I looked at the picture of the chassis in my sams, and it shows the cans as being black, cardboard like.

I asked the guy I bought it from if he did any other work to the set, and he said no.

One other interesting note is that the chassis was not bolted down to the cabinet. The bolts were nowhere to be found. You don't have to remove the chassis to remove the tube in this set.

The owner did mention that this set was in his family since it was new, and was delivered to the house that I picked it up from in 1950. "Bob" also mentioned that he is a Vietnam Veteran. I almost wonder if the caps were replaced in this set while he was overseas. This guy remembers everything, I can't imagine he would forget about recapping this set.

I didn't look that close under the chassis, but I do know that there are wax caps under there.

Who knows?!

Seems like I remember seeing this bad boy's double 1st cousin in a junque shoppe in Knoxville SEVERAL years ago-Way B4 AK, & I don't think it was anywhere close to being in as good a shape. And IIRC, said junque shoppe wanted a king's ransom for it.

Can anyone verify for me that the original Cap cans on the chassis were "Sprague" cans, or were these replacements???

Inquiring minds want to know (mine)!

thanks,

MK

Chances are good that those 'lytics were replaced; the picture just looks too darned good. You could do what I do, and just make sure it is supervised when it's operating, and get ready to shut 'er down if things start getting strange. The set may work fine when cold, and start to fall apart when it heats up.
