I recall from studying the tube manuals that the 28 volt tubes in the R-392
are identical to standard tubes except for the filament voltage. The tubes
perform well at 28 volts on the plate due to circut component values, but
standard 6 and 12 volt filament tubes would work identically. Never
actually experimented to see if there was any difference.
