Schematic
+ BOM
The PCB is designed to take 1/8W
(0.125W) resistors. You can use 1/4W if
you wish, but you’ll have to position them
upright. Make sure they’re bent enough
that you’ll have plenty of clearance in your
enclosure. But really, get some 1/8W.
To save space on the PCB we’ve not
included a separate spot for R4. If you
aren’t using the Ruez mod trimmer you
must place R4 as shown later in this
document.
NOTE: C12 is for power filtering and goes
on the underside of the PCB. Be careful
not to place this right against the board or
you’ll short out the pads around it. You
can only add this cap if you’re having your
DC socket on the top edge of the
enclosure, otherwise it’ll get in the way.
It’s not entirely necessary, so feel free to
leave it out if you really want a side-
mounted DC socket.
*Use R4 or 1KB Trimmer. See next page
for placement.
**Standard Rat clipping.
Replace with 3mm Red LEDs for Turbo,
1N34A for You Dirty.
