Yes I was implying that MIDI was the misuse.  Although B&O used those same pins for their wired remote control as well long before MIDI.  The Revox remote also used DIN but that might have been the 4 pin version which would have been more sensible for MIDI to use.

Well, the Din plug goes back way further than MIDI. See any hifi gear in Europa from then 60’s or 70’s. So if anybody’s misusing the plug, it is MIDI.

It shouldn’t actually damage a MIDI device if it was plugged into one as the MIDI pins aren’t there.

But yeah, we (mis)used DIN connectors like there was no alternative back in the old days :-)

Here’s a photo of mine. Funny, the MIDI warning on the label.

The connector on my Etherwave is a 5-pin connector, so the power plug can be either 3-pin or 5-pin.

I have an opportunity to buy a Big Briar Etherwave Theremin from a friend for cheap. The only problem is it is missing the power supply.
Searching online, I find a lot of Moog Etherwave power supplies.
Does anyone happen to know if these are compatible?
The power plug on the Big Briar unit is a 5-pin midi style plug.
Pictures of the Moog power supply look like 3 pins.

I’m wondering if they just simply removed two pins and the three fit in the midi style plug.
If not compatible, does anyone know where to get a hold of the Big Briar supply?
