Re: Re: AX84 Variable Bias

Everything looks good with those voltages. Actually there is even less wattage flowing through you bias pot because it is in series with a 220 ohm resistor, according to the schematic for the variable bias pot, which is carrying about a third of the load. To read the actual wattage on the pot you just read the voltage drop across the pot itself, from pin 1 to 3 and times it by .045 amps. The pot is probably dropping about 25v and the 220R is probably droping about 12v. That would mean your pot is only carrying about 1.2W. I hope everything works out well from here. If you have any more problems just post them up.
