it would be nice to know if that adapter was AC or DC and what the polarity of the plug was. (just for the curious.) this information is on the back of the plug 95% of the time. sometimes there is a little graphic that shows the pug and there will be (+) pointing to one part. the empeg requires positive on the center pin.

either way, ISTR that the fuse isn't easily user-replacable. Unlesss you're comfortable with a soldering iron, I think you'll probably need to send it across the pond. why don't you email david directly to figure out your options?
