Just remember, you're running the radio with today's 120-125 VAC and the set was designed for 110-115 VAC back in the day.
The power transformer will be pumping out a higher secondary voltage.
Not real good for the longevity of the power transformer in the long run.
Use a buck/boost transformer to lower your AC voltage or a variac and see what the effects are. The BC resistor should get relativelt hot, since it's a wirewound type, but not 'boiling' hot. Your higher AC mains voltage may be a contributor.
