Thanks for all the advice and help I checked and the transformer is 115v only. I bought a 300W step down transformer and that's done the trick, just another heavy lump to lug to gigs in the name of all valve authenticityt!! Pretty miffed with the seller though, not my best introduction to owning a MESA. The story is not yet over though. Amp powered up and going through all the EQ and power options i discover that th1/2 power function produces a noisy overdriven distorted sound. I switch back to full power and its fine? Any ideas??
Cheers
Andy
