Ah, I missed this topic. Lol
Its the Neo 25s I was gifted. Im so close to making one fully functional! But propietary wiring is an issue, as the orevious PSU was made specifically for it and its long gone.
I did find out how it was originally wired, which was weird. All ground on the machine went to a seperate metal playing, which is connected to a AC noise filter and to the main AC ground. So I will just use that.
Waiting on Amazon for the last bits and bobs (closed end Nylon connectors crimpers) and then for the final test!
