Cathode Bias amps, which we do not manufacture use a capacitor to make the grid more negative and do not usually require any adjustment. The downside is they usually have more distortion which make them sound a little more coloured. TT amps feature fixed bias which requires tube adjustment but results in more accurate bias points and less distortion.
