The tally socket connects to the indicator lamps above the screen (lens is missing in the picture). The tally lights on different monitors/cameras were remotely controlled by the switcher in master control, to show which camera signal was being aired at any given time.
I knew a guy who bought the 21" version of this monitor (the TM-21) at a hamfest back in the '80s, but he stupidly gutted it for the transformers and other parts.
The 21" version was HUGE, about the size of a washing machine, but heavier. All hinge-out modular chassis, fully regulated power supplies with a whole buttload of 6080 tubes. Used a 21AXP22, IIRC.
