RCA TK-10A and TK-30A Television Cameras
The RCA TK10A and TK30A camera heads are essentially the same. The differences being in the CCU, PSU and viewfinder. A TK-30A, with viewfinder, is pictured above.
The TK10A is for Studio use and the control equipment is console and rack mounted.
The TK30A is for Field* use and the control equipment is fitted into two portable cases.
* The term "Field" is the same as the UK term "OB or Outside Broadcast"
There are a number of references to the TK-10A & TK-30A in the RCA Broadcast News.
A good one is :- RCA Broadcast News, June 1947 page 56-63.
The first reference to the prototype camera seems to be in # 42 January 1946 page 48.
A short report in Wireless World November 1946 Page 380.
