Very large flyback transformers available:
 
If anyone on the list needs some super large flybacks for experimental work I
have a bunch that were special runs for RRC with 4,000 turns of #39 AWG on the
sec. and a center tapped 16 turn primary already on the core.  Covered
completely in nice grey silicone RTV (dipped in vacuum chamber).
 
These are 10% large than the old 1970's TV flybacks that produced a
steady-state 30 kV DC.  These will also produce a steady 32 kV DC with only a
rectifier and HV diode string.  They also perform great as a HV power supply
with either single wave or doubler rectification (60 kV DC with doubler
circuit) delivering 2-3 mA of steady state current.
 
Operated as a Tesla coil they produce a solid 1.75 inch arc in open air off a
needle electrode.  They light up flourescent tubes, neon tubes, and argon tubes
without wires.  Just connect output to a "radiator plate" of aluminum for
special effects.
 
I have some remaining extra run units that I'm selling off for $45 per unit. 
Estimate shipping at $6.85 USPS or UPS to most CONUS locations.
 
First come, first served on the remaining units.
