Does anyone have an opinion on whether it would matter if the resistor used for filament bias needs to be non-inductive. This design uses a 6 ohm resistor at 35W or so. I could do 3 Mills 12 Watt, 18 ohm in parallel or a Dale 50W 6 ohm silicone covered wire wound. Any thoughts on that?
It needs to be the correct value to get the voltage right. Inductive, non inductive, carbon composition, metal oxide. makes no difference. when induction is concerned unless there is no decoupling capacitor and it is for RF amplification, because the induction it too low to make a difference.
