Wiring shown overleaf will disconnect the battery when
you remove the jack plug from the input, and also when a
DC plug is inserted.
Snap the little metal tag off the pot to mount it
flush in the box.
You should use some kind of heat sink on the
legs of the transistors and diodes when
soldering. They aren’t keen on heat. Any
more than 3-4 seconds of iron and they’re toast.
Recommended assembly order:
Resistors, Caps, Transistors, , Wires, Pots
I’ve incorporated the Current Limiting Resistor for the
LED into the board for your pleasure.
Post Boost..??
The board incoporates a LPB circuit as a post-boost to
raise the signal level. The FY2 has a very low output, and
this makes it much more friendly without colouring the
sound at all.
