If you mean to reform the caps by applying power slowly from a Variac, I'm not
convinced this is the best procedure for tube gear.

Certainly reforming is essential, IMO, but without full filament on the
rectifier(s) the actual reforming voltage may be somewhat unpredictable. It may
also be hard on the rectifier tube(s).  usually leave the set unpowered and
apply voltage from an external PS.
