Hi.
I'm sure the total current would only be in the order of 60ma at the most on a set of this age.
I made up a little supply box from an old wall wart many moons ago which plugs into the variacs output socket, my set up feeds the variac directly from my 2KW isolating TX so its always safe.
I only use this on AC only sets of course, to have the load of the warmed up valves there before applying the HT is very useful, many restored radio's will work on 50v HT with very much reduced volume, interesting to note on a set untouched that they need a lot more HT to give any result than after replacing leaky caps and low valves!
