Wrong voltage Teac MD-H300

I have a teac ref 300 system that was accidently plugged into a dimmable socket intended for a lamp with the dimmer turned down, powered for maybe 10 seconds at most. The amp and minidisc decks have died (the amps power button was turned on, the md has a digital display normallyreading standby, other decks etc which weren't turned on are fine).

The amps internal glass fuse has blown so I'm hoping that will be the cure when I get a new one tomorrow, but the minidisc's hasnt.

It's transformer has a thermal cutout, which needs taking apart to get to. Any ideas first?
