I have a regen radio that uses one type 30 triode tube with 2.0 volt,
60 mA filament. The radio had two 33 ohm 1/2 watt resistors wired in
parallel for 16.5 ohms in series to the tube filament to cut down 3
volts from 2 D cells to 2 volts. I removed these resistors so I could
run the filament off 1 D cell. I now wish to run the filament off 2 D
cells again, problem is I put the resistors in a safe place, now I
can't remember where that "safe place" is. I need to buy a new 20 ohm
resistor but should I use 1/2 watt, or 1 watt? The filament is 2
volts, 60 mA as I previously mentioned.
Thanks,
