12v Neg centre.
It does still work a bit, but the fuzz comes and goes. Sounds very noisy.
When I plugged the power in, the red "on" light came on and stayed on regardless of the switch position. The red light now works as expected but as I say, the pedal sounds like stinky poo.
I know a guy who knows a guy who is currently repairing my Morley Power Fuzz Wah ( non power related issue) so I might just throw it at him when I see him next...
