Alternatives to primary/secondary resistors?
* a variac can be set to give the right voltage
* a step-down autoformer, or a spare filament winding off the HV transformer to modify the filament primary
* "hidden resistors" - small gauge wiring over long distances, common-mode choke, etc.
* replace with a regulated supply - too many kinds to mention all
* ...
