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.
