  Hm. I was kinda afraid of that- it seems there are still a lot of
unknowns in TC work to be nailed down. I can live with that. I like
the loudspeaker enclosure analogy, too, having had some personal
experience there. I'm cursed with perfect absolute pitch, you see.
Most commercial speakers are pure crap IMHO. I guess we're lucky
nobody makes TC's commercially, eh?

  I bookmarked Sam's site some time ago. I was looking at a TC because
I want to build as much of this thing as I can, and I don't need a
whole lot of output current. A TC is such an elegant thing, so few
components for so much results. The voltage requirement is contingent
on several factors I haven't nailed down yet, so I am still exploring
options.

  I keep getting told that "certain things won't work" without any
justification. I hate that and wanted some ideas from experts who, if
they haven't done what I'm talking about, can at least tell me _why_ I
shouldn't bother. Most electronic systems scale nicely (with some
adjustment, of course) and a TC should, too, no?

  Details like how to determine the coupling between coils before
winding them should be straightforward from geometry, but I don't know
how, and was hoping somebody could give me a clue.

  My question about length/diameter ratio was prompted by an offhand
response from sci.physics.electromag; I've since gotten a more
detailed private reply that cleared some of it up for me.

  As for my question about frequency limits, it relates to how often I
want an output pulse, and I established 1 MHz as a starting point only
to be told "no go" again without justification. That, and I'm curious
about how small a TC can be built and still work "satisfactorily".

  Maybe I'm just too lazy, but I want to eliminate certain design
options as "bad" without having to build them first. I also want to
know why just for the sake of knowing stuff, I guess. That may be a
conflict I'll have to resolve with a soldering iron; I should bestir
myself and make a contribution somewhere. If nobody else has explored
this area yet, I may discover something interesting...
