Sorry, no Tesla coil for sale, but sending my list in case you're
interested. The first paragraph refers to a kit I used to offer.

------------
Regarding the "75KV Kit" I used to offer: it seems the characteristics of a
key part in the circuit have changed, and I can no longer get a 4-inch spark
from the circuit. The best it will do is a 3-inch spark (still not bad),
and each kit has to be individually tuned to get the 3-inch spark (all
things considered, still a very simple circuit). Because of all of this,
I've stopped offering the kit and instead I'm offering PLANS for the "3-inch
spark" supply (see below). HOWEVER, I do have ONE kit left and will sell it
for $50 for the "individual tuning" required (plus shipping). "First come,
first served"; let me know if you're interested.
Here's the current list...
