This url is to my Hammarlund Four20 AM transmitter schematic. http://www.hvinet.com/rjmattson/four20schematic The PA 807 screen does not seem to be modulated through a dropping resistor or self modulated with a choke. The Hammarlund Four11 plate modulator is connected in place of jumper MOD on the schematic. Should I try it as is or rewire?
