I've acquired a tr-707 from an american friend who lent it to me with a US power adapter. i went and got a power adapter (12v centre negatve, 400Ma regulated) and it doesnt seem to switch on. there was a very brief second of light from one of the red LED's but that was it... apparently it works though. he's gone travelling so i'm asking:
a) did i just screw it?
b) being from the US, does it require a voltage transformer or something lke that?
c) am i missing something obvious?
cheers.
