Bias Battery
The battery supplies a fixed grid bias to the C3g input tube. As far no current is drawn from
the battery, it will last as long as its “shelf-life” (typically 5 years or more). Replace the
battery if it measure 3.0 volts or less. Symptoms of weak battery are distortion and the C3g
running hotter than normal. Replace only with type “CR2032” 3 volt lithium battery. Make
sure that the battery is installed properly in line with the +/- marks as shown on the picture
below.
