***** Build Instructions *****
- Start off by placing the right-angled headers in the PCB that will house the thonkiconns. Place their straight leads through the holes and cut them off flush with the PCB. Take them out again and cut them off a little more so that you can solder them flush to the board without any stubs sticking out. Solder them.
- Place all thonkiconns on the board, place the front panel on and fasten the nuts. Then flip over the assembly and solder the jacks in place.
- Take the smaller pcb and solder all resistors, diodes, capacitors and ferrite beads. Make sure you solder the electrolytic capacitors as flush as possible or if you are using caps that are taller than 5mm solder them with their bodies flat on the PCB.
- Solder the IC's directly to the board. There is no room for sockets!
- Place the second board on the right angled connectors so that the second board tilted a bit down (towards the side that has no components. Make sure you stay within the 2HP width! Then solder it in place.
- Solder the 1x5 right angled power connector. I left room for a 2x5 connector but these were a little tall. I used the rowo furthest away from the edge. Solder it so that, when connected, the power connector is within the 2HP width.
That should be all. If you encounter any problems or have questions, feel free to contact me via e-mail: belmansander@gmail.com

Questions
How big is the BufferedMult bottom PCB?
It measures 24.8 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BufferedMult bottom use?
23 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BufferedMult bottom KiCad files?
From the DenBelmans/Buffered-Multiple repository on GitHub, at the commit this page was made from: the board is BufferedMult_bottom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BufferedMult bottom design in my own project?
Its repository states no licence, so its author keeps all rights: ask DenBelmans before reusing the design.
