blackstar HT-Dual Schematics

[cymbaline]

Hi everyone

New on this forum and need some help. I`ve got a big problem with this pedal: It sounds great but burn out its external power supply after an hour or less. So i´m looking for some technical info, or even better, the whole schematics. Also if anyone have experimented a similar malfunction ever, and knows what is the problem, my ears are wide open
thanx in advance.
