RE: D70 Output Tubes Drifting WHILE Biasing

Hi Mike,

I would like to remove some tubes as you suggested.

So I would leave in the output tubes, the power tube, and the 12ax7 that is part of the power supply.

Take out 2 driver and 1 signal tube per channel.

Take out the phase splitter tube, which I believe is part of driver and signal tube circuit.

Then I would turn the unit on, and check the bias on the output tubes.

Sound right?
