No bother at all. THe smaller transformers work fine, although the
7.5kV is probably the best to use. THe PVC pipes you have are fine
too. In one test, I used my 6" by 24" secondary coil, and powered it
using a 7.5kV, 30ma NST, with a .0077uF cap, etc. This TC gave
I think 20" sparks or so. I also used a synchronous rotary gap with
