At first I read this as the master, but I think you meant the avionics
master. Did any radio lights come on? Did the transponder do its
transponder blikey thing?

It was the avionics master, yes. Everything but the audio panel came
back on - the radio were just fine, but with a dead audio panel there's
no way to use them!

The 2000 SPs have dual-bus avionics masters. Just curious, did you
try just one side of the switch? Kill the avionics master, turn
everything off by their individual switches and then try turning back
on just the COM1 etc? Also, without a functioning audio panel (if
that's the component which broke) the EMRG mode (click the on/off
switch) should tie you directly to COM1 and give you a radio.

Course, if you're staring at an airport when it happens and not IMC at
the time, the checklist is pretty pointless beyond "turn off power to
all devices."
