I used 2 of the 15kV/60mA F.A.R.T. units for my first coil. They have been
in service for 18+ months and are still going strong.
I suspect you are correct. When they die (not if), there will be no
The RC filter arrangement I used seems to provide adequate protection, see
about half-way down the following page:
As for the toroids, there is a Melbourne company:
48 Koornang Rd
Scoresby 3179 VIC

They make metal donuts for exhaust manufacturers. These have an outer seem
weld you will need to grind-off, lack a center plate you will have to add
and they are raw metal, so you have to do a little polishing
................ but the end result ain't too bad ;-)
The mild steel variants are "off-the shelf" to 10" torus diameter (they
only make symmetrical units, with center diameter = torus diameter, so =
30" x 10"), The aluminium units are up to 8". The larger 10" aluminium
unit I have was a custom job and wasn't cheap = $500AUS or $300US. The
mild steel type are much more affordable, the 8" unit was $80AUS.
Good to see another OZ coiler !!
