If the replacement seleniums are gonna drop the same voltage (and hence wattage) as the power resistor, they would be dumping the same amount of heat, would they not? That's why i thought maybe the problem could be overly high line voltage (verifiable by measuring the heater voltage). IIRC, Phil Nelson had a similar issue with one of his vintage restorations.
