The PCB

I lost the files for the original working board but recreated it from the working gerbers. While untested it should work as it's similar to the working design.

A replica of the aux board PWB111383270000 "sea horse" found in Sound Voltex cabs.

It makes use of a horizontal XH-4 female connector and an unidentified audio jack. For ease of manufacturing I decided to use a more common type of headphone jack (As I was also not able to identify the used jack). The official cycle time of that headphone jack is 5000 cycles. I also could not find any other brands which guaranteed a longer cycle time. While this is not a lot, the cheapness of the part will make replacing the jack a lot easier. The original metal bracket can still be used because the new audio jack is smaller in width.

Questions

How big is the SDVX aux board PCB?

It measures 35 × 35 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SDVX aux board use?

6 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 SDVX aux board KiCad files?

From the veypatch/SDVX-aux-board repository on GitHub, at the commit this page was made from: the board is SDVX-aux-board/SDVX-aux-board.kicad_pcb and its schematic SDVX-aux-board/SDVX-aux-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SDVX aux board design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
