Mike, I had a similar problem with my V2....had to turn the audio almost all
the way up to get much modulation. I replaced all the caps in the first two
audio stages (6AU6's). Now have plenty of modulation. Good luck...Bill K4JYS

Gents, How can I determine is the modulation transformer is still in good
condition? My problem is I cannot modulate to the suggested 250 Ma , getting
no more than 125Ma. I seem to have all the gain I need in the preamp stages.
When acquired the audio mods from ER had been installed but not the
regulated screen supply or the fixed bias on the 807's. All- in-All, it
works but just barely. need to reduce the final input to 80w or so to fully
modulate with mic gain fully open.
Any and all input will be appreciated.( This is my first input to the forum)
