akai headrush (first version) power supply

[skincage <skincage@gmail.com>]

is there anyone who has an EH1 and can tell me the precise power
supply variables i need to match the orginal? my official power supply
conked out and the 9v i'm using powers the unit but produces a very
audible hum. wondering if i can use one with a different mA for better
sound quality or if i should be concerned about the pedal itself being
damaged. thanks!
