Issue No. 159 of Tone Report magazine has an article on how to DIY my mosfet booster. The author was very complimentary of both me and the circuit, which I greatly appreciate. If you don’t like working with stripboard, as shown in the article, there are pc boards and completely assembled modules available on my catalog page so you can build your own mosfet boost.
The pcb and modules have a refined version of the circuit that improves performance slightly.
