Hello,
This is an idea for driving the output off a tube mic preamp (front end comming next).
The two halves off the tube drive the signal in the same voltage phase, but in opposite curent phase (same amount), current consumption remaining theoricaly constant.
This is an Idea I found in some John Broskie documentation (Tubecad).
What do you think I can expect from this design in terms of performances and drive ability ?
I know I could modify B+, Bias, and the two 10ks res. , but It'll be cool for My project to keep arround 20db gain for the stage...
thanks for any comment, analysis, and advices.
