When I started in television, in 1969, the station
was an RCA "house". Meaning we had all RCA
equipment from the cameras to the transmitting antenna.
You could build an entire TV or radio station from the
RCA catalog at that time, with very few outside vendors
of equipment.
The film chain we had at the time was a TK-27 camera, which
did use vidicons, a pair of TP-66 projectors (16mm), the
slide projector TP-7 (IIRC) and the multiplexer(mirror system)
was the TP-15 (IIRC). The TK-27 used 4 vidicons, one for
the monochrome picture, and the other 3 for color. There
was a mode which allowed for operation with just the color
tubes, if the mono vidicon failed.
It was a tricky beast to set up, I could do a passable job,
but my boss could make it sing and dance.
Later on, about 1978 we bought another film chain, a TK-28 which
was available with either vidicons or plumbicons. The plumb was
a vidicon with a lead oxide based target. That film chain never
really looked as good as the -27, but in a few years, with the
advent of one inch VTRs and Sony Umatic, TV operations started to shy
away from film.
The transmitter (TT-6EL)was a tube type,
and there were still some tube type picture monitors, but the majority
of our equipment was solid
state. The VTRs were a TR-3, and -4, with a TR-5 (anyone remember
them?) in our truck. At that time the gear used mostly germanium
transistors, but silicon was starting to show up.
We had just received a pair of TK-44A color studio cameras in 69, which
used plumbicons, silicon transistors and integrated circuits.
The main thing about RCA gear as I remember, is that it needed a lot
of PM (RCA= Requires Constant Attention), but it was generally
easy to fix.
And then there was the TVM-6 microwave equipment. We had a microwave
system from Sacramento to Elko, NV and spent many, many hours on the
road keeping that stuff running.
