Thank you.  I've been trying to avoid batteries.  I did have a second 
RS-70 which had a terminal permitting the two to be paralleled.  This 
worked fine delivering 100 amps for a Henry SS-750.  Unfortunately I 
sold one of the supplies when I got rid of the Henry (when will I ever 
learn?)

I wonder if it would be possible to replace the filter capacitor with 
one with a lower ESR or parallel it with another one, etc. if this is 
the weak spot?
