Power Supply for Big Briar Etherwave?

I’ve got an opportunity to buy a Big Briar Etherwave from a friend but unfortunately the power supply is missing. 
I haven’t had any luck finding a replacement online. The Moog power supplies are what come up when I do a search and from what I gather, they are not compatible.
Does anyone know where I can find a power supply that will work with the Big Briar?

I found this one on EBAY:  https://www.ebay.com/itm/334430260092?hash=item4ddd98cb7c:g:88oAAOSw0tZic47h
Better grab it they do seem to be getting scarce.

That is for the Moog version, not the Big Briar. As far as I can tell they wouldn’t be compatible because the Moog is 220V and the Big Briar supply is 14V

Why do you think the Moog and Big Briar power supplies are not compatible?  I have both and I don't see any difference.  I use them interchangeably.

(The ones I have are US power supplies, but I don't know why the Euro versions would be different.)

P.S. 220V is the input and 14V is the output.  All Big Briar and Moog Etherwaves expect a 14VAC input.

I’m in the US as well, so wouldn’t need a euro version. Yes, maybe I was confused because they keep calling the power supplies 220v. I thought that was the output. Now that I’m looking again, I think you’re correct.

I own an old Big Brier and the Etherwave Standard.   The power supplies are interchangeable. P.S It's still available on EBAY.

OK, I get it now.  There are no Moog US power supplies for sale right now, so searches are only turning up the 220V Euro version that Adorama is selling.

US power supplies should have the 110-120V box checked on the label, but it seems like they often didn't bother.  As long as it has a US plug, it's the right version.  Either Big Briar or Moog is fine.

I guess you could ask Moog if they still sell them.  Or, buy a generic 14VAC wall wart and solder a DIN plug on it.

If you were really stuck you could buy the 220V power supply and add a 120V->220V stepup transformer to it, but that's unappealing.

It seems like authentic power supplies are getting scarce. Mine still works, but I know several people that have lost or broken theirs.

I found a 16.5VAC grounded power supply on Amazon (designed for home security systems):
https://www.amazon.com/gp/product/B0CYWPBR96/

And the appropriate DIN connector:
https://www.amazon.com/CESS-Male-3-Pin-Connector-Soldering/dp/B01FQ6NC7K/

The EWS should be fine to take 16.5V rather than 14V; in fact the original Big Briar Etherwave schematic specifies a 16V input. The AC input goes straight into a dual LM7812 linear regulator, which is nominally rated for up to 36V.

I will order the substitute power supply and build up a custom cable to test it against my original model, then write up a guide if everything checks out.
