Schematic + BOM
*The original circuit uses
C2240, but you could try
other BJT. The circuit is
basically a Big Muff Pi.
C2240 have a nonstandard pin-out so there
are extra pads on the PCB
to accomodate those and
standard CBE cans. See
later in this document for
more info on that.
**NTE102/3 in the
original, but you can try
other germaniums. We
supply AC128/AC176
which work well. You
could replace these with
silicon if you prefer.
