Gyratone Booster

[Paul Marossy]

Anyone build Joe Davisson's Gyratone Booster?

I'm just wondering what that transistor arrangement at the source of the JFET does... Does it make an asymmetrical waveform or is it akin to a tone control of sorts?

And, of course, how does it sound?

Hi,

can it be a kind of ToneControl?

If i had a J201 i would try it...

All I know is that it sure has me intrigued... Joe always comes with interesting things.
