It's sad that most stations only saved the camera heads and junked the support equipment.

Its my understanding that the TK-41 didn't come with a color encoder. The camera output was pure RGB. You had to purchase a separate encoder (usually from RCA I'm sure) that would do the job.

I'd expect that once you have the power supply ratings (and have the camera recapped and ready) it will probably just power up. The problem will be in figuring out the control signals, because I'm sure that even in an early camera like the TK41 there were probably lines devoted to the remote control of various items like focus current, etc. Additionally, what are the returning RGB signal levels, and what pre-emphesis was applied by the amps in the camera? You have to reverse that and amplify the RGB signal again to modern RGB levels so that you can feed a modern encoder. I'm sure there's more that I don't know of. Its definitely not for the faint of heart.

I once played with a TK-41 on its tripod, but have never operated one from the CCU side.

I actually have plenty of them for what I need. I was asked if I wanted it but he wanted $1000 (plus shipping) for it. I may have 5 or 6 spares.

Whoa ! A kilobuck ?!? Think I'd pass, too, especially if I had as many as you have.
