The Midiverb/fex housed into a 19" 1U rack with PSU ...

This Midiverb had a severly damaged plastic box and a dead power supply.
I have adapted the PSU to work with a +/-15V transformer and the thing into a 19" 1U rack, with I/O jacks on the rear .



Home made power supply for the Midiver/Midifex . It is a 220V/ 2x9V 30VA transformer.
