Nice curves that might be important, but he doesn't say what he
connected to the input.
Tonight I will connect one of those fet-IC's commonly used and a 60
pf condensor from gate to ground instead of a mike capsule, all put
in a screening tube.
Then it would be appropriate only to switch pip on and off..?
Agree?
