Last US station(s) to use Iconoscope cameras???

[Electronic M]

Probably PBS(then called NET) affiliates, college and community stations. The early television museum in Ohio has a field van from a NET station and much of the equip that they were using in the 60's and 70's was late 40's gear that was donated by other stations. There was a great video shot of crew from that station recalling the experience at a convention a few years back. I believe they called the place the only the place "the worlds only operating TV broadcasting museum" back when it was on the air....Much of the equipment was older than the teen age crew members!

I'm still chuckling over the fact that someone actually named a tube "pesticon"....
