Once the bias is set at the required
settings, lock down the trimmer lock
nuts by turning the nuts clockwise while
holding the trimmer shaft with a screw
driver so as not to lose the setting. Do
not over tighten the nuts, just snug them.
Once complete, return the rear baffle
panel to the rear of the amp and fasten
it with the screws you removed and you
are done!
BIAS CHART (Measurements are for two
tubes per bias point)
Note: The range setting is for experimen-
tation. Power tube bias settings change
the sound of the amp and the range listed
above is safe for experimenting. The larg-
est setting is considered the maximum
setting and should not be set above this
setting. Running the tubes on the higher
end of the range will shorten the tubes
expected life.
