Tim,

Ok, if you already have the NSTs ready to go, then go for it.
I assume that you're trying to keep the individual components
of your coil portable then? You'll have to be careful with Res
rise and over volting of those NSTs though or those NSTs
could turn into some rather expensive "boat anchors". Though
I don't personally have much experience with synch rotary
gap systems, the general consensus amongst this list is that you
will need to run a multi-NST system with a synchronous rotary gap
(SRSG) and a larger-than-resonant (LTR) priamry capacitor
to protect those fragile NSTs from Res. overvoltage. The "Terry filter"
seems to protect the NSTs pretty well from overvoltage, too, but I
don't think that it's designed to work with an NST farm quite that
large! With a pole pig, you can easily run with an asynchronous
rotary spark gap and a smaller-than-resonant (STR) primary cap
without any problems.
