Introduction
The Purple Fuzz is a personal take on the classic Octave Fuzzes. It has been specially adapted so it will
fit on a small pcb with integrated 3PDT footswitch. If you want it as original as possible you can leave
out D1 and jumper it with a spare piece of lead wire. Be warned that you will not have polarity
protection anymore if you leave out D1. If you want to leave out the LED than do not solder R22 and
the LED.
Building sequence
Soldering this board can be very complicated for some people since the solder pads are very close
together. Use a magnifying glass to make the job easier. If you want to experiment with other
transistors the
n you could socket them instead of soldering them to the board. You’ll need a 20
SIL,
break off the sockets and solder them to the board.
Start by soldering the resistors. If you want to socket the transistors then solder the sockets now.
Note:
Do not blow on your solder in an attempt to cool it down. That will possibly result in a bad join
that might corrode!
Solder D1, the ceramic capacitors and then the small SMF/MKT capacitators, D2 and D3, then the
electrolytes, finish by soldering the 3PDT footswitch to the board. You are free to choose on which
side of the board you will solder the footswitch, just be sure to test if it fits your enclosure before you
solder it!
Place the transistors and you are almost ready to rock.
Besides the components mentioned in the Bill Of Materials table, you will need:
•
2 input jacks
. 2 mono jacks if you are not going to use a battery but only the 9V adapter. 1
mono (for output) and 1 stereo jack (for input) if you will be using both a 9V battery and the
9V adapter.
•
1 x 3PDT footswitch
(9 pins)
•
2,1mm DC jack
(isolated).
•
9v battery clip
(optional).
•
22 gage stranded hook-up wire.
•
1 x LED for status
•
Hammond 1590B
case (or similar) in your favorite color if you make sure to use the smallest
possible components. A
1590N1
(or
125B
) will give you more space to work with so I advise
that is you have some bigger components.
