TUBE
BIAS CALCULATOR (for push pull class AB1/AB2)
Select Tube Type and
the Plate Voltage of the amplifier below. Recommended
range for
setting plate current and/or cathode current will be calculated.
Note: The low end of the suggested range is the
"cooler" setting, for cleaner sound and longer
power tube life. The high end of the range is
for warmer and thicker sound, but with resulting
shorter tube life. The higher the setting, the
hotter the tube temperature.
