TK-31 camera control unit

Went to the local hamfest today...my how they have shriveled...and found this CCU for a 50's TK-31 sitting in the back of a SUV. $10 later it was mine. Seller had it for 30 years. He got it from a tv shop he worked at and the shop got it from a local TV engineer. Likely Philadelphia Ch. 6 or 10. No markings other than "3" as in Cam 3.

Side panels were long gone. Dirt and packing foam laying on the bottom. It is a combination B&W monitor and oscilloscope waveform monitor (3KP1). It needs a separate power supply and sync generator in similar suitcases to run and the interconnect cables. None to be found so it is just a display to go along with my prop TK-31 from other threads. The setup could use a fourth suitcase that was a five input switcher. I cleaned it out for display after the photos.

What CRT does it use? I'm figuring just a standard 7JP4, I don't see any yokes in there so I'm going to stick with electrostatic deflection...

I'll admit the photo of the jacks on the back has me slightly aroused. I do miss the silly types of plugs that were used prior to damn near everything going super tiny. SCART vs HDMI is a good example.

I think it is a 7CP4 left over from WWII use in drone bomb receivers. It has an odd bulge a the base of the bell before the neck. It mounts straight-in from behind the glass bezel.

The odd jacks were very clever by RCA. They were all different so only the proper jumper could be used from suitcase to suitcase connections.

Nice find! :-)
