Don,
I would advise against using your radio on 8 volts. Not particularly good for
the tubes for one. Also will supply too much voltage throughout the radio. Even
the use of dropping resistors is not recommended as the filaments draw less ( I
think) amperage when cold than warm, so if you get a resistor the right size to
supply 6 volts when the radio is warm it will supply to much voltage when the
filaments are warming up. This would be somewhat less of a problem dropping form
8 vrs. 12 volts and perhaps the tubes will tolerate it, certainly using the
resistor is preferable to running it on 8 volts all the time. The way I
determine what resistor to use if by bench testing with a bat, voltmeter, a a
big variable resistor as in 20 watts or so. Once I'm satisfied the resistor is
set up to supply the correct voltage I measure it with a ohmmeter and buy a
fixed one the same value. This could be figured out mathematically but I'm never
sure I know what the load (amperage) is exactly.
