I don't know, but I'll try it and report back the next time I am where the set is (probably tomorrow). On the other hand, mine has just been regunned by Hawkeye, so it may no longer have RCA filaments.....
You could hang a meter (preferably analog) across the filament and see how high the AC voltage gets when you turn it on. The filament is floating at probably about 200v DC above chassis ground, by the way.
