Re: questions on old school TV studio equipmet

I'm not familiar with any of the gear mentioned, but I'll take a shot at this. I'm going to assume that the RS-110 is a CCU (camera control unit) for the BY-110 camera. The aux input on most CCU's is reserved for sending return video back to the camera head, so the operator can view e program feed or whatever the engineer routes to the aux input. In short, you can't use the box to sync a composite signal - you need a TBC if that's what you're trying to do.

With regards to the cameras - they are probably good for museum pieces or giant paper weights. The old tube camera's had to be realigned on a regular basis. Even if you had an engineer realign the tubes the picture would still be terrible. I would guess that those cameras are 20 years old. The quality of imagers has changed quite a bit in the last couple of decades.
