Some nice 1950's RCA tube technology. I lifted the one w/out lenses onto cart for pictures. It's heavier than it looks but I wanted to get the feel of what it was like to work with these things in the 50's.

Nice photos, great looking unit! I know QTQ-9 and NBN-3 in Australia used these TK-31s as illustrated in my thread http://videokarma.org/showthread.php?t=247571 I am on the lookout for any units that have been preserved by collectors, museums or possibly stations and am hoping to find at least one surviving specimen.

.. I know QTQ-9 ..used .. TK-31s ..

I've seen those cameras in studio and later [reassigned to Remote truck service late 60's] covering Springbok demonstration ~1970.

They were replaced in studio by Fernseh solid state Monochrome I.O. [model?] using Fernseh OS-20F [3inch?] I.O. Which were, in turn, replaced with LDK-5 in '73-'74.

Don't know what happened to RCA's or Fernseh's - did see Ampex 1000 there up for grabs, taken by tech staff member who attempted to get it running [needed special power connection for deck + associated racks].

TVQ-0 had RCA TK-60's? [Cool!] & ch 7 had Marconi which I think I saw one camera in Bris themed restaurant ~1980 w/ vintage B'cast equip.
