sort of, it will jump about 6mm between 2 bits of wire.
6/7kv?

no this is a half dead 50kv lab inducion coil (made in
india, lol) in a neat wooden box, with the interupter now
removed and driven by a 555 ic and a 2n3055 transistor at
230Hz, square wave. it arced over internally when i was
using it's primary in series with a mot primary to to make a
varing magnetic field for a transformer experiment. took the
actual coil out and potted it in wax but it didnt help.
output is about 15kv now. the arc cooks bugs nicely...

Can you be more precise about the

4 blue 270v caps, 2 1kv ceramics from a cordless phone, 1
250v cap from an OLD psu. all in series. that amounts to
abou 3.5kv...

What kind of spark-performance are you getting?

out of the tc i am getting lousy 1" arcs to ground
