STARTING YOUR AMPLIFIER FOR THE
Once you have the tubes installed and the power cord plugged in, the volume control
all the way down (counter-clockwise) you are almost ready to turn it on. BEFORE YOU
DO, we need to familiarize you with the BIAS controls. There are only two and they
are extremely easy to operate. (after the amplifier is turned on and properly
biased, we will connect your source component.)
We'll start with the most important of the two controls, the one in the front of amplifier
located between the two meters. It is a small 1/4 inch shaft with no knob on it. The
knob is not used because this control is seldom adjusted, and a knob makes it easier
to accidentally bump it out of adjustment.
KNOB and it is simply used to make the two meters read the same value.
In the picture above you can see the meter on the left is for the KT88 output tube
directly behind it. Same for the meter on the right. These meters show how many
milliamps of current are going through each output tube. Since this is a push pull
amplifier, the objective is to get both tubes to draw the same amount of current so that
they match. This gives the best performance and the most power.
