An NOS '49 Motorola 7VT2 TV
 
4 Attachment(s)
I couldn't pass acquiring this one. It's practically new, both chassis and cabinet. It still has the inspection tag tied to the CRT socket and all the marking and stampings are like new. I came with it's original box and operating manual. I will have the chassis gone over by my friend and get it working once again.
One of the most appealing little early post-war TV's made.

Nice set :yes:. The crt looks like it has the cadmium phosphor, original.

Thanks. Interesting about the CRT. It definitely looks original. Even the metal around it shines like new and the tape strip holding it on looks like it was just placed there.

Very very nice! Thanks for sharing.

Thank you guys. In case you're wondering, the last owner recapped the chassis, so the option to leave it factory original is out. It's okay with me because I like to play my sets. Right now it has issues, but will be gone over by my repairman soon.

Yow...a true time capsule!

That's pretty cool. Hopefully they restuffed the factory tubular paper caps...I sure would on a factory original like that if I planned to make it work.

Amazing score! I'm glad it ended up in your hands :yes: It looks like the knobs don't have the white crud that so often plagues these sets.

I'm not sure what you mean ? Why would this TV have a different phosphor ? Doesn't every 7JP4 have the same type of P4 phosphor ?

Thanks Bob. It wasn't exactly a bargain, but I couldn't resist it. It glistens like new in and out.
Yeah, I too have never heard of a particular phosphor on a 7JP4.

As nice as that TV is I personally wouldn't consider calling it new old stock. Realistically anything found as NOS should have all the original components still under chassis, as well as all the original packing materials. Basically an unmolested and unopened item as shipped from the factory. Just my opinion of course. Otherwise a beautiful specimen. :scratch2:

Amazing! It’s as if it had come from a time capsule.

Technically yes, but when you look this set over, it's hard not to want to push it's description towards "NOS". I'm surprised the previous owner did elec work to it without at least re-stuffing the old caps, but in a way I'm glad I don't have to stress over "should I or shouldn't I"! If I was to leave it untouched I would just sell or trade it. I dislike static display sets.

Hi Bob,
I recall reading in some old literature that the chemical elements for the P4 phosphor were changed in the 50's. The percentages of some the chemical elements were varied. The older crt's tend to look much yellower. I see this difference in many of the sets I have with original crts. The newer 7JP4 like I bought in 1974 looks more gray/white. I even noticed this on a 5BP4 I bought from the ETF a few years ago.

Every major manufacturer could (and some did) vary powered phosphor color... unpowered phosphor color can be as much a function of runtime as manufacturing process. If you have encountered a round tube that sat behind a square mask and was set up for minimal overscan there will be a browned center square and a blue outer ring.
