Phase Inverter

Post by David Root »

How about the PI? Assuming the standard long tail Schmitt design, it draws only about 2mA w/12AX7 and 4mA w/12AT7 (usually--I notice Ken Fischer's Komet 60 12AX7 PI draws almost 4mA, but he has 476V B+ too!). However, does the amount of feedback affect this in any way?
