Soldering the pcb

First, the printed circuit board is assembled by means of the placement schedule shown below. You should decide at the outset whether t he B uffered or True Bypass version is built. In the true

bypass version of the unlabeled components need not be loaded (loading images in the description)! For this we should start with the lowest components to be fitted, ie first the 2

bridges (Br), resistors, diodes, IC sockets, capacitors. Then the circuits are used at the end. Clean work, especially the execution of the solder joints should have top priority to generally be eliminated in order to save a painstaking troubleshooting from the outset assembly and solder defects.

After the PCB is fully soldered to cut several wires from approx. 10 to 15 cm le ng th and solder them into the points of the circuit board to which the potentiometers come from below. Next up is the enclosure that it has drilled before accordingly with the mechanical components (6.3 mm jacks, 3PDT switch, potentiometer-[the (guide tabs) to easily breaking the potentiometers with pliers from Æ see the picture.], DC jack and the bezel for the LED equipped.) The wires for the power supply (red an d b lue), as well as the output signal of lug 2 of th e level pots, are already pre-wired.

Wiring the buffered version

The two green wires in the wiring diagram is soldered directly under the circuit board at the marked points.!

At the appenidix you found templates for a drilling and a templete for a foil for the enclosure. When printing the PDF files, the printer must set to "No adjustment" otherwise the print is not true to size

Finally, only the remaining connections are soldered displayed schema from the switch to the PCB according to the above. To do this turn the circuit board on the compon ent side. To solder the Green wires in the wiring diagram, (buffered version), from the bottom of the circ uit b oa rd where the both 68 k and 100 k resistance are connected, as well as the two GE diodes.
