Some older Orr radio handbooks are available for free download.

Reforming capacitors can be done with any HV supply hooked to a variac. Ramp up to working voltage slowly and watch current. Any heating means the ramp is too fast.

Caps that have been turned on in a circuit after extended non-use may be damaged.

Caps used in voltage multipliers are not good candidates for re-forming.

Variac-ing entire pieces of equipment with the hope of re-forming caps causes more damage than just powering them up.

Be wary when trying to series up high voltage secondary windings. The working voltage of the windings can be exceeded and the xfmr will zorch.
