From the vendor
How can so few parts make such a good boost? I don't know. I am not smart. But Tim Escobedo is since this circuit is his Duende Jfet. But it is better known as the JHS Mini Bomb since it's the same circuit. Shame on you JHS. Also shame on me since I kinda do the same thing. But at least I tell the people wich smart people came up with the circuits. Okay now I am getting defensive. Who are you to judge me? Who am I to judge me? I am getting carried away... This is a good boost. Will probably give you a very good drive if you put two of them in series. I didn't try it i am just throwing the idea out there. But maybe I am just trying to make you buy two PCBs. These long descriptions are getting out of hand. I will just stop now....
