So I need 2 approximately 21 ohm resistors rated at least 2.5watts eh? Guess I should use 4 10 ohm power resistors? I have the 2 boards wired up in parallel to the transformer should I put 1 10 ohm resistor per heater supply connection wire, or do 2 in series from the transformer to those wires? Or 2 in series on only 1 side of each heater supply? Sorry, this was actually my first diy amp and honestly I think I'm doing pretty good if my only problems are I broke 1 1$ mosfet and my filament transformer is giving me a bit too much voltage/current.
or is it .33a = 6.3 / R, R = 19.0909 so I = 7.1/19 == .372A and to get .33A I need an additional 2.5ohms? (.33 = 7.1/R, R= 21.51515?) guess I will find out when I get home regardless ;p.
