I'll get a good close up pic of one of the towers (wound 4 of them now) to show everything.
L1 is approx 400 turns of mid 30's enamelled wire from 2x RF-300 or RF-310 Mabuchi motors.
L2 can be either 2 turns or 3 turns of 'bell wire', which is, I believe, 22 guage. The spool the wire comes from does have a sticker on it, but someone in their wisdom decided to test a Sharpie over the label ! It appears to be of the same gauge as .032" Rosin Core solder from Radio Shack.
The L2 coil placement does affect performance. Likewise, there is a massive difference depending upon transistor used, Known plasma producers include MPSA06, HN2222A, C3242A and C3198. Many others will produce good plasma if ones finger nears the output wire end.
I'll be posting a .txt in a few minutes related to transistors, which also may be of use
