Leiterplatte
As the first the circuit board is soldered with the help of the layout diagramme illustrated below.
Moreover one should start to equip with the lowest components, i.e. as the first the resistors, the
diodes, the capacitors and at last the transistors.
As the last one solders from approx. 6 to 8 cm long Litzen in the holes of the Potis. (Easier from
the bottom side)

When the circuit board is finished, it is fitted to the assembly of the mechanical components in
the enclosure and the external wiring. Given that enclosure is already prepared with all the holes.
The LED is used so that the short leg (cathode) shows to the switch.
The 3PDT switch place in the enclosure so that the groove is either up or down in the thread of
the switch.
The input jack should be wired before that. (2 wires to ground (sleeve), ring Æblack wire from
the battery clip and tip of a wire, which then goes to the switch.
The wires from the battery clip you can cut the black and can then also take for Tip.
The connection switch Æoutput jack provides you the easiest forth with a piece of wire cut from
a components.
This is all done, the prepared PCB with the potentiometers and the SPST switches are connected,
and the external wires from the switch and the power supply to the circuit board only needs to be
performed. This solder is conveniently right from the bottom of the corresponding points. The
attachment of the circuit board in the enclosure by means of the supplied self-adhesive spacer
directly on the two two potentiometer..

Notes to the mechanical structure:
The small tabs at the potentiometers are easily broken off with pliers (see illustration on page 2).
The 10.5mm steel washers are inferior to the jacks. The 7.4 mm for potentiometer As knobs
which you should use with a max. diameter of 24mm, when a pre-drilled 1590B enclosure size is
used. The holes in the jacks sit 14mm from the bottom of the case, the DC jack 12.5mm from the
bottom.
The 10K trimmer should be to balance the symmetry, but no differences were apparent. Neither
left nor to the right stop.
For self-drill:
Potentiometer: 7mm
Jacks: 9.3mm
3PDT switch: 12mm
DC jack: 12mm
LED bezel and SPDT switch: 6mm
If clean up and properly wired, the effects device should work immediately. For any questions we
are always available.
