I forgot to mention that it was the "home/car not recognized" problem that made me open up the empeg and examine the AC sensor switch in the first place. Apart from that, the empeg was working fine.

My power supply (european?) doesn't open. There is a small device at the plug end of the cord but its not a fuse.

I'm a bit reluctant just trying another power supply, won't I destroy it too? Perhaps getting one with a fuse is the best solution.

Has anyone else managed to destroy their power supply, or blown its fuse?
