I’ve found myself in a situation that I have a spare clouds, want a reverb for my prophet 12 and had a thought!
So the question is would a 12v AC wall wart be stable enough to supply clouds? or would it need filtering etc? Or does anyone know of a single module case psu? One in actual production.
The wall wart alone is not enough. You need a dual supply with +12V and -12V which can be made easily from an AC wall wart. Some soldering is required, though.
Look here for schematics and instructions

It’s not even a matter of being stable enough.
A 12V AC supply provides a voltage oscillating between -17V and +17V (at 50 Hz or 60 Hz depending on the country you live in). That’s an entirely different thing from the two steady +12V and -12V rails that Clouds need.
You could power Clouds, in theory with two 12V DC supplies. But that wouldn’t be a very practical thing to do.
how would you do the dual 12v DC? I have a pile of them so they are free right now, same with rails I have small rails etc … the optimum thing is is it cheaper to do than a Doepfer mini PSU board, if not… I simply buy one of them, or sell the clouds and buy something better suited to the job.
( keep in mind there’s already a clouds in the rack so I’ll still full o’ grains )
erm … doepfer mini psu = £39 / patch box £349.
PSU 1 + = 12V
PSU 1 - = GND
PSU 2 + = GND, tied to PSU 1 -
PSU 2 - = -12V
But if a reverb is what you’re after, I’d say sell the Clouds and get a Lexicon MX200 or MX300. Clouds doesn’t really make sense without modulations anyway.
I have an MX-200 so it’s for going in a bag and travelling light, I’ve got an SBX-1 I use for USB midi that has cv out, so a tiny clouds running the parasite for the massive reverb and modulated freezing etc, ipad to sequence the 2 will be fantastic and then a 4 way adapter everything will power.
I’m unfortunately moving to a much much smaller space than currently and most of the keyboards have become desktop versions and I sold a full tiptop space case and 9u of modules off.
(Lots of heartbreak! I had my analog keys for about a month in full before this re-location was agreed)
Thanks again for the help
