Steve,

Yeah, I know, but Tom seemed a bit concerned about sticking his mitts in 
there.   I think we are all trying to tell him in various ways that  as 
long as he is unplugged, nothing bad will happen to him, either from the 
a.c. or d.c. sides.

I still have a feeling that on the inside  this screw may be  the 
connection to chassis ground for the a.c. line cord, and he would be 
better off getting it tight.
