Hello
This has to be my favourite JFET based drive. Standard Barbershop & my estimate on what the Millenium edition might be. I've built it and it works a treat.

- Equally as important is correctly biasing the JFETS to the correct drain voltage. I ended up using 15k resistors on the drain of the Sprague JFETS in my builds
