RCA TK-60 (A) Television Camera side open

This is a picture of my TK-60 camera in a rather sad state awaiting restoration. The Cue dome and the fan housing are missing from the camera top.

The TK-60 has an interesting arrangement with the focus action. One of the design problems with 4.5” I.O. cameras is the weight of the scanning yoke. This becomes a problem when the camera tilts up or down and the, now out of balance, the yoke makes the focus knob/lever very hard to move. Indeed the yoke could career catastrophically to the end of its travel! RCA solution to this problem was to counterbalance the yoke by moving the electronic chassis on the other side of the camera in the opposite direction! You can also see the moving chassis at the top with a heavy transformer on it.
