Using your DMM, adjust T1 until you get approxi/4.5v (depending on whether or not you are
doing pos. or neg. ground) reading on the collector of Q2. The Zygote is set up to provide a very wide
range for biasing. Note that if you order PNP transistors from Smallbear, Steve typically sends along the
values to correctly bias that particular set. You can sub in the values he indicates, if you like. If you still
want to use the trim pot, adjust it so that the resistance on the pot + the 220R in series with it adds up to
the value he indicates for the collector of Q2
