Has any one traced or have the schematic for the Dunlop (CAE Custom Audio Electronics) MC404 Wah?

I've had a good look in the files but cant find any thing.

Cheers Geoff

Bumping an old thread again...

Does anyone have one that could read the code off of Q3? A friend plugged in the wrong adapter and fried it :/

For the previous poster, you can get the circuit running again by jumpering 9v+ to the non-grounded side of c13....I'd just like to replace q3 if possible to ensure good power filtering, just need to know what the hell to replace it with!



**Oh yeah, and could a mod move this to the correct board? Thanks!!

Fixed! Q3 is a PNP - I used a 2n5087. E to 9v jack, C to the circuit, B to the diode->resistor->ground.

Also - FYI: Q3 is an MMBT5087 (SOT 23 package). It's equivalent in TO92 is the 2N5087.
