Hi hywelg,
Thanks for your suggestion.
I think I've found the power supply dedicated to my board. The Decibel Eleven power supply : http://www.decibel11.com/Hot-Stone-Deluxe-Power-Supply.html
This one seems to be compliant with my 9, 12 and 18V pedals and my huge 9V 1200mA.
In France it costs 170€ (approx : 192.362USD).
Best regards,
Benoît
