Found this in the basement boneyard of local NBC affiliate. Should have asked the engineer what it was.
Called a MONITRAN TM-30A RCA # MI-26499 Has crystals on turret type channel selector but front controls suggest it might be a modulator ? |
I dunno what it iz, either, but me likey the Box its takin' up residence in....

Very cool. I've been lookin' for a rack to house my BT modulators.

Those "Boxes" are in high demand by the Boatanchor Boys....They can go for silly big money on You-Know-Where. Especially ones like that, w/an opening lid...You can crack it open for ventilation, or leave it open, which makes it look like you're "working" on yr R-390A or SP-600, & know what you're actually doing...GREAT for poseurs like me...

Edit: Or meant as a TRANsmitter to allow use of TVs as MONItors. A MONItor TRANsmitter. |
Can't read the labels on the knobs - that would help!

RCA used the MI prefix for a lot of commercial items, for example sound equipment like the crossover networks used in the public address system for the 1964-65 New York World's Fair. I would like to know what MI stands for. The prefixes of their other products were usually decipherable, like "CTC" - "Color Television Chassis."
Edit - Could it be "Military-Industrial?" |
After some searching, found this page indicating that "MI" stood for "Master Item" number.

I had one of those...
...about 30 years ago. There should be a little RCA emblem above the pilot lamp. I still have the emblem mine came with. I honestly don't remember what happened to the machine. I probably traded it to someone for some other super-cool toy. I used to do that a lot. Occasionally I think about it and wish I had it back. :sigh:
It is a modulator, and if I remember correctly it did B&W only, no color It was crystal controlled for each channel. PL259s for everything on the back. I can't say it was the exact same model as that one, but it sure looked a lot like it. I may have a snapshot of mine somewhere. I guess I'll need to dig for it. |

Yes , I took the emblem off mine and added it to my 1940 RCA tube amplifiers (foto) along with the Deco chrome red pinstripe trims. I sold the amplifiers with these RCA badges still on (mistake) but still have the decorative strips on my audio rack (previous post foto). I would be interested in buying that emblem to restore this piece if you have no further use for it. I'll have to re-cap this unit and fire it up and see if I can get it to pass color ? |
