Since there is no established numerical system for the Stax jack, what is pin 1?
1
2 5
3 4
Edit. Can't get the code to function correctly so this will have to do.
Like this or something different? Anyway, using the above system then each pin is 2.35mm wide and the distance (measured outer edge to outer edge) of pin 1 to pins 2 and 5 is between 10 and 10.05mm. Pin 2 to pin 5 is roughly 13.23-13.25mm. Pin 2 to 3 and pin 5 to pin 4 is roughly 7.77-7.80mm. Pin 3-4 gives me 7.81-7.84mm. The only 6 pin connector I have is on the SR-1 and while it fits alright, the odds are it has been bent a bit in the last 40+ years.
