Is It Hot In Here Or Is It Just Me?
Here’s an RCA TK11 with all it’s doors open to cool off. This shot is from CBS Television City from around 1956 and taken on Stage 43 where ‘Climax’ was done. It was an anthology show with different live dramas each week and was much like ‘Play House 90’ and ‘General Electric Theater’. Unlike local station cameras, network cameras were on 8 to 10 hours a day and the tubes put out more heat which could cause the viewfinder to go out.
Still a common problem.
Take note of the CBS built custom viewfinder hood. CBS. like many, did not like the RCA snout VF hood. I have made one similar to this one for my TK-11B.
wow
Same thing happened with the TK42s during a telethon in the early 70s at WBTV in Charlotte, NC. A few hours into the telethon (Jerry’s kids, I believe), the cameras all started misbehaving. We had to open the covers to keep them operating.
This happened in both studios where we had one studio with the telethon and the other with the entertainment acts.
I read that if the Orthicons are overheated, you have a loss of picture resolution…
cool off the cameras and a chance to have a smoke
