Wow, I knew that this thing would eat a lot of power, but this is pretty excessive:
The tv tube filaments alone add up to 9.4 amps!
The radio filament string will require 2.7a
The phono filaments, .6a.
The 5y3 plates will need to supply 440v @ 85ma, the 5u4, 270v @ 160ma.
So now, where to get something like this? Playthings of the Past has a nice list of spares here:

The closest thing that I own in my spares is a transformer to an rca T120 from the late '40s. It boasts a lot of tubes, but seems to fall short for my purposes:
700vct @.22adc, two filament strings: 1.2a and 9a
