Hi, I have since a couple of weeks back started to read about Ed Grey's tube after i was looking at Morays ion valve, and i came over this pdf from Panacea about this guy called Gary Porter that made a sort of Ed Grey Vibrator motor, and i couldnt find anything other on it except from that pdf.
If you want to check it out just google Gary Porter Panacea pdf or something.
Have anybody heard about this before?
