And then something else.
I would like to perform a bias mod on the Dual Rectifier.
What I often see what they do is remove R255. Here comes a potentiometer with a resistor in series (so that the tubes cannot burn out when the potentiometer is fully screwed up)
The wires of the bias switch are soldered loose, so that it is no longer usable. Because the bias is adjusted with the potentiometer.
Now I would like to keep this switch and its operation, but instead of one potentiometer, I want to apply 2. One for the setting of the 6L6 and the other for the EL34. Now I have made a design. I assume this should just work, or are there any comments ?!
