[Amps] AL-82 Blowing fuses on startup

[Gary McAdams]

Hello Group.

Short question: I have an AL-82 that has started to blow a fuse on start-up.

It doesn't do it every time, and when the fuse is replaced the unit 
starts OK and runs all day w/o problems. This all started when I 
re-arranged the shack. The unit is about two years old.

The first time it happened, I checked the AC input at ~248 volts. Is 
this too high?

So, any ideas on what to look for or where to start? As I sit here the 
amp is on and running, but yesterday I had to replace a fuse to get it 
started. This is only twice that I've had to replace the fuse, but 
that's two times too many.
