14 | jack 3 pin with switch | 4 | ||||
15 | jack 2 pin with or without switch (no switch at the jack needed here but feel free to use the same as above) | 28 | ||||
16 | 20pin header (you need in total 40 pins) | 2 or 4 | ||||
17 | 20pin socket (you need in total 40 pins) | 2 | when using 15mm spacer or 4 when using 20mm spacer | |||
18 | metal spacer (to hold the pcb) 15mm long M3* or use 20mm spacer | 4 | ||||
19 | nut, washer, screws M3 - that match to the metal spacer | depends on spacer | ||||

Steps to your completed device:
important Info: the logicboard is mounted with the components thru the ucb and lcb boards - like this:
please read the guide before you start the build to understand my preferred guide, its possible to assemble the module in other ways too !
Logicboard
- start with the assembly of the Logicboard, don't attach both long headers !
- begin with the resistors you can solder from component side and turn the pcb - solder from solderside too.
- place and solder the rectifiers and ferrite beads
- place and solder the IC sockets (dont fit the ICs)
- place and solder the capacitors
- place the Power header (4pin MTA156) from solderside as shown here:
ucb & lcb PCB
Warning |
---|
make sure you use 3 pole (switched mono jacks) for the 4 top jacks ( IN A IN B , IN A IN B) |
...
- prepare the long headers: the distance between the controlbaord and logicboard must be 14-15mm, the big WIMA 4.7uF caps
the pinheaders are 7-8mm high, connect 2 together.
mount the male and female header together - the boards have a silkscreen layout for the 6,3mm jack - this is the component side !
- mount on the frontpanel with 4 jacks in each corner on one pcb, solder one pin on each jack, thats needed to have enough space to solder the pin headers like this:
...
14. if 13. is ok - add all ICS and test the module
testing process Active Splitter
