Emax

Hi !
I did a PSU replacement on a Emu EMAX S.E. rack some months ago... The 
original PSU failed in a capacitor and schkotty diod ... I never find 
those parts in my area, and a new psu was around $80 (but as i'm living 
in belgium ... the cost is much more expansive with additionals taxes). 
So i did the "swap" myself between a typical ATX PSU and the original one...

It's really simple. Just use a voltmeter ... A typical ATX can provide 
-12v / -5 / +5 easily (the ATX psu is much more powered than the emu 
one). There are enought space inside the Emax. I used a special glue to 
maintain the PSU.
The sad side is you'll get the PSU fan noise but the sampling process is 
not affected (noise parasits ...) !
The ON-OFF Wire on a ATX psu could be found here :

You have to close the circuit between PS_ON & a GND pin to get the PSU ON.

Hope this help,
J/M
