Building
This is simply a suggestion - you might find a different workflow more practical:
1.
Mount the Banana jacks onto the front panel.
2.
Use a side-cutter to separate main pcb and component pcb.
3.
Mount the pots onto the component pcb. Pots should sit on the side facing the front panel (as
marked on the board). Don‘t solder them in yet.
4.
Carefully mount the component pcb (with the pots inserted) onto the front panel. You may then
have to wiggle each pot a bit to get the pots through. Make sure the threads of the pots go
through completely and the pots sit right at the front panel. You can even screw the pots to the
panel to make sure of that, but you will have to unscrew them again later.
5.
Once everything is nicely in place, solder the pots onto the component pcb (while the front panel
is attached). DO NOT SOLDER THE BANANA JACKS YET!
6.
Stuff the main board, beginning with the resistors, then caps etc.
7.
Main pcb and component pcb are to be connected through precision DIP socket and pins. It is
recommended to use the pins on the main pcb (facing down, soldered from above) and the pin
sockets on the component pcb (standing up, soldered from the front panel side). Break or cut off
the pieces you need and stick them together so that main pcb and component pcb form a nice
sandwich (don‘t solder yet). Check that you didn‘t leave out any pins / holes and that the sockets
are all on the same side (component pcb). Solder all the pins in while keeping the sandwich
together - this avoids any misalignments.
8.
Carefully separate the sandwich - if you used precision sockets, this may not to too easy - they
stick together nicely (giving a good connection).
