- Page 8 Dustbunny Notes • There are a variety of NPN silicon transistors that will work in this build. For mine I did the following - Q1: BC108, Q2, Q3: BC207B (140hFE and 160hFE, resp.) You could use all BC108/109 or find a cool mojo mix. Smallbear has plenty to offer for Tonebender types. Generally smaller gain buckets are better (300 hFE and below).
