I am thinking in building an AM transmitter for 7.1 Mhz (40 meters) using a
EL34 in class C as final.
The idea is to modulate it by varying the negative polarity of the
suppressor grid (g3).
Suppose I load the EL34 plate with 500 volts DC and a current of 150 ma with
0 volts suppressor, does anyone have any idea what negative voltage in g3 is
needed to reduce the anode current by half, needed for screen AM modulation ?.
