With just 19 watts of power available, either the tubes were powered
down while not in use, or they were indeed exotic vidicons. A lot of
power was saved by not needing high speed sweep circuits for the tubes.
In fact, I wonder if those weren't electrostatically deflected. Higher
voltages, but less overall power.
