Hi Al,

	In general, they do add in a linear way.  So if you double the NSTs, you
double the PFC capacitance.  However, that assumes that the primary
capacitance doubles too.  If you leave the primary cap the same, then two
transformers will be driving that primary cap value.  So you would use the
chart number for 1/2 the Cprimary.

	Just think of it as two completely separate primaries that you are
paralleling up.

In general, Adding PFC caps will cut the current draw by about 1/2.  Thus,
you can run twice the NST on the same variac and AC line fuse.

Cheers,

	Terry
