fellow synth geeks,

I turn to you for help with finding a good power supply for my yet-to-be-built schroff rack. I have read a few other forums and got some tips and searched eBay a bit, but quickly got confused. I'd rather not get the Doepfer wall-wart solution. My electronics knowledge is not up to speed with power supply malarkeys, apart from knowing that I need +/-12v, 5v, and 0v.

I know this has been asked before but any help would much appreciated.

Thanks peeps.

do you have any modules that require 5v in your system?

i recommend power one PSUs. you might hear them hum (not in the systems signal paths!), but that is part of the deal wink

however, they are sturdy, and i would say unbreakable. they are even used in aviation. once i bought a 20 years old PSU from a guy in canada. it still works without any problems.
you will find some good offers at ebay, i bet.

i dont require 5v in my euro system. ive been very happy with:

power-one HAA15-0.8-A

i picked up four surplus units for about $9 each off ebay.
a couple of them required some nasty desoldering work on the output terms (i HATE flux fumes :barf: )

anyway they are reasonably small and provide 1000mA on both +12v and -12v.
im using one to power 4 euro racks (no BBD or digital modules in the rack though).

you are so fast! eek!

i use currently 3 HAA15-0.8-A.

it is similiar to a mannesmann unit which i have the datasheet from. a little bit more information than power one delivers:

I emailed Tom at ASol about delivery cost etc, and he said:

There is really very little DIY if you know how to solder.

The directions here:

are excellent.

I just finished DIYing a euro case and stuffed it all into:

http://www.ikea.com/us/en/catalog/products/44361109

$5 worth of wood to make rails and mount Doepfer busboards, and without rack ears I managed to squeeze another 12hp of modules into each row.

No need to do that necessarily, but don't let the PSU scare you. It's already built. You just need to wire things up. And not die.

Almost all my modulars are powered with power-one psu's.
I got them all from ebay and they are the best i think!

I'm wondering if I can just put the Power One (12V 3A) in my 6U rack and run a line from that to a busboard in the 3U rack and just run both off one supply.

cheers for the responses peeps.
hopefully going to pick up that power supply tomorrow; got a schroff rack to build and I might knock up a little wooden house for it.
only thing I need now is a bus board! d'oh!
