  20amps, wow. Someone give me this for christmas!

I now have Two nice machines (Tek scope, VT100) that blow 
fuses and have been dancing aound the issue to get one for a
few weeks now.  I'm not really an electronics guy but I've been
led to believe that a variac is the single best thing to get to help
remedy fuse blows.  Any strong yes or no votes towards this
decision?

Hi
 If you've hit a capacitor hard enough to blow a fuse, it
is not likely to recover through reforming. Reforming
must be done before applying full voltage.
 Most issues of blowing fuses can be located by isolation
and use of an ohm meter.
