HELP with Rocktron Banshee TalkBox

[pabloevaristo]

I received my banshee talkbox, tried it and worked. Then I change de power adaptor (I´m in Spain, so we use 220V and I didn´t want to use a 220->110V transformer).
I didn´t realize that the original adaptor is AC/AC, and the one that I used is AC/DC (al the other characteristics are the same).
The led was on, but no sound from the driver. I changed to the original adaptor and..... NOTHING.
It´s not working at all. The other 2 outputs are working when I press the pedal switch.
Any idea please?.......

Of special interest are the actual voltages *and polarity* at "+14.5V" and "-14.5V". The +5V and -5V may also be interesting. Voltages at the OUTput pin of each amplifier stage may also give clues.

By the way, that schematic has an error. Polarity of D6 does not make sense.
