I managed to pick up a vintage graphic fuzz about a year ago which at first i thought was great until sourcing a power supply for it became a big issue. A 40v power supply was virtually impossible to find until i found a power supply company in Denmark who made a multi-power supply unit called the powerbitch with 3 9v outlets with one 18v, 24v and 40v. Didn’t work which leads me to believe the pedal only takes 40v with 500ms or its either broken. Any ideas?

Finding a schematic for those pedals can be a serious pain but i know a couple of vintage dealers and specialists here in Ireland dealing specifically with ehx products so if i come across anything I’ll let you know.
