This should be fun (RCA TM-10 15GP22 monitor)

[Phil Nelson]

He probably got wind of that rotten B/W Philco I rescued from the E-waste recycler and thought, "Man, I bet I can sell that guy anything!"

Phil, you are going to have to update the name of your site to Phil's Old Radios & Televisions.

how satisfying would it be to sit and watch a movie or a dvd of a television show from the early colors days on this!i love this and it is in good hands now.

Sugoi!

I'd start playing the lottery if I were Phil......

"Its ID plate says MI-40206-A, but the ETF website says it's a model TM-10, so that's what I'll call it."

RCA professional gear often had a type number (TM-10 in this case) and always an MI number that appeared in the catalog book/price sheet for ordering. Even the crossover networks used for the public address/music speakers at the 1964-65 New York World's Fair were specified by MI-number, which allowed me to track them down to determine the circuit used.

Phil, nice to see you got it, unlike the sarcastic harpoons above! Just kidding and seriously, glad that you got this monitor and especially glad that the kinescope is good. How many can there be out there?

[Sandy G]

Yeah, despite all the frivolous noise I make when something like this is scored, I can't think of it going to a better home than Phil...Or any of several more of you guys here that have the technical smarts to truly do it justice...I most certainly DON'T.

Great score Phil! Look at all the lytics in that thing; certainly an impressive find. Please post pictures for us to follow on its progress! I look forward to seeing some stills of the picture it produces once you’ve got it dialed in. Bill

My very first TV station job had one of these monitors in prop storage. I could see it, I just couldn't get it out of there, or I would have owned it. Too much stuff between it and the doorway. I did wind up with a TP-6 RCA projector, though.

Congratulations on this find. These things are really scarce now, eh?

A nice overview of this monitor (and lots of early RCA color broadcast gear) available in a 1954 issue of RCA "Broadcast News" here:

http://www.americanradiohistory.com/...77-01-1954.pdf

The site has many other issues available for download, as well....

[holmesuser01]

Great reading from this. Thanks.

Alot of the broadcast equipment I got to see was from this era. Unfortunately, its all gone now. Hmmph. It only sat there in storage for 35+ years!

I hereby nominate you for the most significant historical find of the decade !!!

And as others said, I don't see any chalky crap in the tube, so maybe you got a military-spec version with a good seal!

The tubes that went into studio monitors were likely hand-selected from the best production tubes available. Is the tube in this monitor labeled as a standard 15GP22 or does it have a special number?

[Phil Nelson]

Thanks for the kind wishes. I promise to treat this thing right.

When I first heard about it, I contacted John Folsom, who advised that it's an interesting set and well worth getting.

The CRT is stamped 15GP22 (and PAR under that, whatever PAR means).

This will be a long term project, so don't expect exciting news any time soon. Today's big achievement was unbolting it from the pallet and grunting it onto a metal table where I can start to clean it up (photo below).

The previous owner also has a B/W monitor for sale, round CRT, model MI-36052. If anyone's interested, send me a PM and I'll get you his contact info.

Unless somebody knows what PAR means, we could guess - here's mine:
