Raven Labs Ringbox Retro
An artist from Texas was looking for a replacement / fix for the 9 v bipolar powersupply for his beloved Raven Labs MDB1. They are discontinued :(
I came up with an alternative to use my power supply retro fit without him having to be without his favorite piece of gear.
Used with a standard Boss style 9V < 200 mA .. painted white to match :)
