Nocentelli JFET Boost

Here's a recent design by Nocentelli. A single JFET stage into a Baxandall EQ stage with a BJT gain recovery stage. Originally designed with an opamp gain recovery stage and no gain control, Nocentelli redesigned it for a lower parts count and easier build. I added a trimmer to the JFET stage so it's easier to bias correctly. More info here on FSB.

  1. Hey, I built this. It's super clean booster. With this layout you can have a eq with control volumen but the gain pot only up more the volumen don't add distorsion.I don't know if it's correct, I'm beginer. Thanks for your job. You can tag as verified.
