Why not try and get the best out of it while it is still 4' long? I
am sure most people would be interested to hear the results. I would
anyway. 1500 turns in 4' doesn't sound overly excessive in terms of
small wire diameter. I have thought about using such a coil to
replace a Marx bank by giving it large primary shots and just using
it in single shot mode.
