Monoscope
$676
 I suppose that's because of the womans image  http://cgi.ebay.com/ws/eBayISAPI.dll...m=130378307189

Wow! that is not your usual 2F21 (Indian head) or 1699 (custom) monoscope tube. I think that i have seen the womans picture before in articles about early tv... I am looking, and will post if i find something on this tube and when it was used.

Is that tube being powered up to get that image or can it be seen with it off?
Never mind, I see where it is.

The monoscope has been identified as the "Girl's Head" type 1898 by CRT historian Peter Keller who sends these scans of the data sheet:

Dave Johnson demo'd his monoscope that he nicknamed "The Lady in the Bottle" back at the first Early Television Convention. (Certainly not something you see every day!)

If I recall correctly, Dave's monoscope was not a RCA tube. Please correct me if I am misremembering.

Yet another lady? This article shows a small 2" monoscope that produces an image of actress Joan Blondell made for/by the American Television institute. The display screen looks a little phony, IMHO
However, it does appear to match the image that can (sorta) be seen at the front of the monoscope tube.http://uv201.com/Tube_Pages/monoscope.htm Unfortunately one link in the article does not appear to work  jr Last edited by jr_tech; 04-05-2010 at 10:48 PM. Reason: add pix
