 One thing that puzzles me is that all these things seem to imply
 powering the system's own power supply with a Variac rather than
 bypassing it. Wouldn't it be possible to have connect a linear
 transformer with the proper output voltages to a backplane and then
 power that with the Variac to reform the caps only switching back to
 the stock supply once the caps have been reformed?

The Variac transformer works because the voltage is AC. The crew at
the CHM used a programmable DC power supply to reform the capacitors,
after they disconnected them from the system..
