Pete,

Seems to me that if you have more turns, then you have more inductance, i.e.
more voltage, given everything else remains the same. This would work up to
a point until wire resistance (using thinner wire) and inductance reached an
equilibrium.  Am I wrong?

	I like minature things. I've been experimenting with a small TC,
3.5x10" 
	secondary, for quite a long time (years...).

	Last weekend I decided to rewind some of my secondaries (there are
some
	advantages to not coating them!...)

	I had these three, all on the same size 3.5x12" tubes
		450 turns #24 wire
		570 turns #26 wire
		667 turns #28 wire

	I always got the best sparks from the #28 coil.  That had a lot to
do with
	uping the the primary Cap at the same time, and getting up to a
"resonance" 
	sized cap with the #28 coil, putting more energy per charge into the
primary
	circuit.

	I had always wondered where the progression would end. Last weekend
I
	unwound
	the #24 and #26 and rewound them so now I have (again all on 3.5x12"
tubes)

		667 turns #28 wire		(6"-diam 7-T, 9.6nF,
primary)
		990 turns #30 wire		(6"-diam 10-T, 9.6nF,
primary)
		1320 turns #32 wire		(6"-diam 13-T, 9.6nF,
primary)

	and now the #32 coil seems to get the best sparks.  This time it is
with
	the same resonance-sized cap in all cases.
