[R-390] thanks

R390A leakage:
A long time ago I had a PK-232 and a dot matrix printer set up for AP 
wirephoto reception.
The audio feed was from the R-390A.  At some point the circuit board in the 
printer "went west".
I was quite some time before I figured out that it was the 60VAC from the 
R-390A ground that caused the damage.
Since then I make sure there is a ground on the '390 and there has never 
been another problem.
