Dynaco Tube Amplifier question of the day

Question How do I install dual bias adjustment pots. in my Dynaco Mk 3 amplifiers?
The Dynacos are 60 watt tube monoblock amplifiers,which have a single pot. to adjust the bias to the output tubes.This warrants the use of matched pairs of output tubes.I would like to install two pots.so that I can adjust bias to the output tubes independantly,and allow the use of unatched tubes.

Best Answer Yes, you could do this. But by using mismatched tubes, even if the DC balance is set properly, you will increase distortion in the amp as each half of the audio waveform is amplified a different amount and on different non-linear portions of the tube's gain curve. But if you should insist, then the easiest and best way to achieve balance in this amp with mismatched tubes might be to replace the common cathode resistor for the outputs (11.2 Ohm 1 Watt) with a variable resistor network rather than tampering with the tube bias circuit. Email me for details. WK
