If you were asking me, I believe I checked the voltage and found it to be
reasonable. It has been a long time since I've changed them out. As I said,
the new ones have been in there since! But I know what you're talking about,
I've done likewise in a few other types of radios! I can't speak for the
others' whose radios I've heard of with the same problem. SM

30 years ago I was a broadcast engineer at a B&W TV station. The
projector bulbs in the RCA film chain were rated for a 20 hour life at
120 volts, and they were pretty close to that figure. I couldn't depend
on a steady supply, so I adjusted the Variac in each project to run them
at 100 volts, and got over 300 hours out of every bulb after that. The
color temperature was out of spec, but you couldn't tell, because
everything was B&W.
