Anyone know the spec / part number for those square white 9-pin connectors between the transformer and filter box on WPC? The ones where you do the voltage configuration.

I must have looked at a hundred images of 9-pin 3-row connectors yesterday, but couldn't find the matching ones.

Thanks, does look like they have the receptacle, but no plug housing.

Neither Digikey or Mouser have them: no wonder I couldn't find it there, no image.

I guess these are obsolete and difficult to find.

Are you sure? I noticed that too on many of the images when searching, but these seemed to be ungrooved and have the angled corners and latch in the right relative positions, unlike many others. I believe the exact parts would be 19-09-1092 and 19-09-2092.

On one of my machines it had a nice AC tap patched in between these connectors, I wanted to make a few more taps for powering various accessories like a validator or amplifier. So I need compatible connectors. I may give up on that, might be overkill anyways, but I liked the idea of easily moving the tap between machines. I might just wire in some 2 or 3-pin molex onto the pins to tap into that way.

I did ask G-P-E if he could check in on this thread already.

I looked again, I think you're right, the housing does have the grooves. These seem to be the similar parts, maybe one version doesn't have the grooves. Are you saying the physical size doesn't match though anyways?

Did a quick survey: 5 of 6 of my WPCs, both of my System 11s and a Sega are all using the connector I pictured, so that seems to be the original.

But I suppose it is pretty easy to switch to readily available connectors since it's just switching the pins over, so I'll probably do that.

I ordered the Molex 42021 series ones, since I noticed many of my Sterns use that one. At least I'll be compatible with those ones.
