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.
First decide which charge pump you want to use.
IC2
can fit a LT1054 or even the cheaper ICL7660S.
When using the 7660S, you must place a jumper in
J1
! Do not blow on your solder in an attempt to
cool it down. That will possibly result in a bad join that might corrode!
If you want to experiment with other diodes then 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.
Note:
Glass
diodes are fragile. Do not expose them to heat for too
long or they’
ll break!
Start by soldering the jumper (if needed), resistors and then the diodes (if not socketed). Solder the
IC socket next and then the small SMF/MKT capacitators, the DIP switch, the electrolytes and finish
with the
C3
silver mica. If you want to use a regular 22pF MLCC for
C3
, you can use the
C3a
pads.
Do not yet place the IC (and diodes if socketed). Wait until after you soldered the potentiometers
and switches.
Besides the components mentioned in the table on the page 4, 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.
•
3PDT footswitch
(9 pins)
•
2,1mm DC jack
(isolated).
•
9v battery clip
(optional).
•
22 gage stranded hook-up wire.
•
LED and LED flange.
•
Hammond 125B
case (or similar) in your favorite color.If you need more space, use a
Hammond 1590BB.
