buba FET

I've been noodling with a MOSFET driver for a champ, SE 6v6...
Really fun , MOSFET can make some really big voltage swings perfect for driving
control grids on power tubes.

But,... I never tried them in a hand dressed rig, its been a steep learning
curve figuring out what not to touch with probe tips while the circuits up and running.
So used to taking voltage readings in tube rig, good thing they're cheap.

Other than that they're surprisingly rugged .

Can anyone point to so good practical resources for MOSFET.
I've been enjoying the thought of tube hybrid design.

hey appreciate it... I stumbled upon this pdf just now.
Figure 4, the test everything circuit is practical as a RC stage.

Hi Andy. I´m thinking about trying a MOSFET grid buffer to solve a crossover distortion problem in an amp I´m making, a modded AC30. I searched the net but there´s very little schems available, as a matter of fact I only found the R.G. Keen one. Do you by any chance have a circuit you could share? Sorry, no answers for you, just questions...

Thanks
