[739] Superhot Mosfet Boost

Mosfet Mini-Booster

This is a copy of a page from the Analog Music Projects Newsletter, that I first published over 9 years ago, which shows a high gain mosfet mini-booster type circuit. I saw something similar at DIYstompboxes and thought I would point this out to the purchasers of the newsletter to review if they are interested in the subject and would like to see more info.

The AMP1 newsletter also describes how to make bipolar silicon and germanium versions, as well as more than a dozen variations of srpp or mu amplifiers. Check it out!

Mosfet mini-boosterThe top transistor can also be a mosfet device, which gives you an all-mosfet mini-booster.

Start out with R3 = 1M and R4 = 2.2M to bias the upper mosfet. Try this with two BS170 transistors for a clean unique sound.

Can you teach me how to run circuit that similar to this on dual supply? What needs to be changed? Thanks before.
