-grin- Thanks, John.  I do see the powerful merit in your fuse-hot-only 
technique.  I really do.  But a short of the hot side to chassis would pop the hot 
fuse, not the neutral one, wouldn't it?  Remember, I am using a three wire 
cord with direct bonding of the chassis to my third-wire ground.  

I will admit that the condition of the thrid wire grounding can be suspect in 
some buildings - I've found some where the thrid pin was not connected to 
anything, or was very poorly bonded to something that might be grounded somewhere 
-grin-

In either case, more than one failure in a row is required to result in a 
dangerous situation.  As in a primary short to chassis, and the rig plugged into 
a badly wired house.  But that badly-wired house is just as likely to have the 
hot and neutral reversed, so that under a fuse-hot-only policy inside the 
rig, now the hot is riding the neutral into the rig with no fuse in line.

There are a lot of permutations, aren't there?  We can only do our best to 
cover as many and the most likely ones...
