the old bandit control. I have no idea of it's Va rating. It puts out
46 volts AC. Its the old stacked plate type, not a toroidal. The
actual coil measures 5" dia X 4" tall. Any idea what the Va rating
would be? I'm thinking about 800 Va. Judging by the size and ratings
of presently available units.

Ron,

The power handling depends on the core area (bigger is higher),
frequency (higher is higher) and magnetic properties of the core
material. There is some useful information here:
