I own several Zero88 desks which use the 4-pin DIN PSU connector: Level 6 DMX (grey one, if that matters), Alcora Mk1 & Mk2, and Diabolo. Each desk has the PSU pinout marked next to the connector and they all show Pin 1 as +9V DC. (I'm not worried about Pin 3 as none of my desks have analogue output.)
However, the instruction manuals for the four desks (as currently on zero88.com) specify different voltages for Pin 1:
Level 6 & Alcora Mk 1: 9V
Alcora Mk2: 10V
Diabolo: 12V
A support post by Zero88 states the same PSU "0010211" is suitable for all these desks (the post seems to have been deleted but you can find a cached copy in Google): http://support.zero88.com/Legacy-products/Legacy-Consoles/Jester-12-24-24-48/975068111/Replacement-External-PSUs-Power-Supply-Units.htm
The actual PSUs that were supplied with these desks seem to be a mixture of "10V" unregulated (these also have the 20V on Pin 3 for analogue) & 12V 2A regulated SMPS (no 20V on these).
So, my question is: can I use the Zero88-supplied PSUs interchangeably with the above desks? If I need to replace a PSU, is a 9V or 12V regulated power supply more appropriate?
