Hi. Glad it's sorted. I ordered it as a UK voltage amp, so have no idea if it was adapted or how. I have now remembered (sorry) that the original fuse blew because it was the US standard one, but I replaced it and all was fine for ever afterwards (as far as I was concerned), and I assume that means it was done properly - it is offered as an option at point of sale. Hope it doesn't go wrong again, although I guess fuses do blow from time to time. If it's any help in increasing your confidence in it, I've now had 3 such amps and have had no problems...
