It has been suggested I add a string of diodes in the
center tap of the Filament Transformer in my Swan Mark
1 amplifier for bias. This is a Zero Bias amp but
bias is suggested anyway to ensure a stable bias
voltage. The tubes in use are a pair of 3-400Z tubes
in GG.
I like to gather a variety of opinions on questions
like this because I learn so much from the various
opinions.
73,
