I have an old "Industrial Instruments, INC" capacitance decade box that
gives me a capacitance range from .001uF to 1.11uF (model DK2A) and I was
wondering if anybody would know what voltage this would be rated for.  I 
took it apart but I didn't see any ratings on the caps inside, and I was
wondering if I could use this to "tune" my primary supply for power factor
correction.  I don't want to hook it up to the 110V line and toast the caps
if they can't take it.
