WebOct 7, 2024 · (1) Fixed Bias Fixed bias in the FET can be obtained by supplying with the battery voltage. The terminal gate must connect with the negative supply of the battery and no current flow is evident through the resistor. (2) Self Bias As the name suggests if the external supply is not provided for the circuitry. This type of bias is known as self-bias. WebNov 12, 2014 · Example: You know the amp has roughly 350 volts on the plates. You know the EL84 is a 12 watt tube. You divide the wattage by the PV 12w/350pv = .034 Thats 100 percent dissapation. Then take your target idle current ,say 70% (70% is considered the high side-you can go cooler/lower) so multiply .034 X .7 = .024 or 24 milliamps. how to remove oil stain from silk
