New PCBs, 6/5/2020

Eight new projects available now: Runoffgroove, Way Huge and more!

It’s been awhile, but the first batch of new projects for 2020 is finally here. Four of them are Runoffgroove favorites, and then four more drive circuits are joining the family.

Several of them use J201 JFETs, which we now have available in SMD format pre-soldered to adapter boards so they can be easily used in through-hole designs.

Runoffgroove Peppermill PCBRunoffgroove Peppermill

A super-simple drive created by boosting the signal into a J201 JFET until it clips in a tube-like manner.
