Admiral Color Adapter.
I had always though those Color Adapter sockets seen on some models of early 50's sets was to allow for use of a color wheel on an existing B&W set, according to this it was to allow your existing B&W set to receive Color Broadcasts (in B&W) if the CBS Color standard had been adopted.
That explanation makes a lot more sense. In any case this has to be a very rare item! http://cgi.ebay.com/Antique-TV-Admir...item4cf8b3dc94

Apparently this gadget was designed to be used with or without a color wheel (you just wouldn't get color without the wheel).

Gosh, I hope Admiral didn't make up too many of those. I suppose that most went in the dumpster. It's pretty amazing how this one escaped.

Anyhow what I meant to say was: From what I get after reading the description existing B&W sets would not have been able to receive the incompatible CBS color broadcasts so some manufacturers made sets with the option for a plug in adapter so they wouldn't be obsolete. They would still have been B&W but able to pick up the color shows in B&W, which the RCA compatible system allowed without any adapters or modifications needed.

If someone here gets this they'll need to find a compatible Admiral model, lot's of them around I think, feed it a show using a CBS Color signal and see how well it converts it to NTSC B&W!
This really is something that need to wind up at the ETF!

 The difference between the B&W standard and the CBS color standard was mainly this: receivers made for the former were incompatible with the latter due to a difference in scan rates. ISTR a distinction being drawn between *adapters*--which allowed color broadcasts to be received in black & white and *converters*--which provided for connection to a color wheel. The gadget in the auction is referred to as an adapter-converter. Notice it has a three-position switch--standard, b&w-from-color, and color. From what I understand the image size had to be reduced for use with a wheel on larger screen sets. So the second switch position would allow you to watch a CBS show full screen--in black & white--and the third position would shrink the raster to fit a wheel. In either case the device only changed scan rates of the receiver, it didn't actually convert CBS to NTSC.

I see, a little less exciting then I suppose, still rare though.
I have a Wilcox-Gay branded Majestic that has a color jack on the back but I think it's only three pins and not an Octal plug, it is wired into the chassis however.

"In addition to the standard black and white pictures which it originally received, your set is now equipped to receive black and white pictures from TV * color signals, or color pictures if a color wheel is used." * Meaning the 441 line CBS 24x3i color signal (or 72i B&W), but not the still not invented in 1951, NTSC color signal.

One of several Admiral 1951 ads touting "Color TV Optional", I assume this ment the Admiral color converter in the e-bay auction.
http://imageserver.lib.duke.edu/dc/i...ed/TV0008.jpeg Probably saw color on this bar equipped model with out the color converter. Lol: http://imageserver.lib.duke.edu/dc/i...ed/TV0014.jpeg -Steve D.
