20v 1.7a 3-Pin Din Power Supply

[Barnee]

Just got an email from some keyboard specialists I reached out to last week and they kindly sent over the attached images. On the PSU you can just about make it that out says:

(1) +20Vdc, 1.7A
(2) -20Vdc, 1.7A
(3) GND

I also managed to find the attached datasheet for the connector type online which includes pin numbering - do you think it's likely the pin numbers will match?

I don't really know what I'm looking at when looking at the image of the main board, but you can see the the power connector. Are you able to give any advice / attempt to cross-reference against the above info? It seems like it's not clear which pin goes to which line due to the direct PCB mount, but perhaps you have a better insight as to the implied route than I do.

Assuming the connector datasheet applies to the exact plug you bought then there's a good chance the pinout numbering corresponds to what you have listed. If you get a magnifier and peer closely at the plug you will probably find 1,2,3 moulded into the plastic. It's a pity the PSU_US.jpg isn't a bit sharper, since it seems to have a picture of the plug on it.
