The power and signal pads on the PCB
conform to the FuzzDog Direct Connection
format, so can be paired with the
appropriate daughterboard for quick and
easy offboard wiring. Check the separate
daughterboard document for details.
Be very careful when soldering the diode
and transistor. They’re very sensitive to
heat. You should use some kind of heat
sink (crocodile clip or reverse action
tweezers) on each leg as you solder them.
Keep exposure to heat to a minimum
(under 2 seconds).
Snap the small metal tag off the pots so
they can be mounted flush in the box.
Positive (anode) legs of the electrolytic
caps go to the square pads.
C6 and C7 can be laid flat to the PCB as
shown on the cover image. This will give
more clearance in your enclosure.
Negative (cathode) legs of the diodes go to
the square pads.
The controls on this circuit are very
interactive. A little tweak here may require
another tweak there.
TRANSISTOR PINOUTS
Manufacturers can be very unhelpful
sometimes. Different versions of 2N2222
may have different pinouts. Check your
datasheet if sourcing your own parts.
If you’re building a FuzzDog kit, your
transistors will be one of the following:
PN2222 - these should be mounted as per
the component silkscreen on the PCB, i.e.
flat side of Q1 to bottom of board.
P2N2222 - these have the opposite pinout,
and should be reversed.
