Factory Bias Settings

At this time, all 3P amplifiers are Fixed Bias.

NOTE: Bias adjustments can only be performed by a qualified service technician. Do not attempt to adjust the bias yourself. Lethal voltages exist inside the amplifier and can injure or kill you.

Utilizing a 1 Ohm resisitor to ground on the output tube cathode, the following list indicates each model, tube type and factory bias setting:

HD100: JJ E34L (30mA)
American Dream: Winged-C 6L6 (33.8 mA)
British Dream: Mullard EL34 (33.5 mA)
Dream Solo Models 1 - 4: JJ 6V6 (32 mA)

Tube Rectifier and Solid State Rectifier?

At this time, all 3P amplifiers are Solid State Rectified.
