Hi All,
I'm not sure if this is the right place to ask this, but I'm
sure sombody out there will be able to help me. I built a few of
those simple flyback drivers with the single 2N3055 transistor and
I have experienced a few problems. They are a bit too weak to
drive my 12in argon filled plasma globe, unless I parallel 4
transistors, and that blows out my step down transformer (it pulls
like 6 Amps, the transformer is rated for 2, and a single
transistor pulls about 1.8 A). Is there a better transistor I can
use? or will I be forced to get a huge step down transformer. Any
input would be appreciated, and if this is the wrong list for this,
I can go elsewhere, it is no problem! (but I'm sure sombody out
there knows what to do).

P.S. the frequency shifts all over the place with just one, making
consistant plasma impossible at low pressures, but this goes away
with 3 or more transistors. Also, I need a transistor that won't
make an audible scream, as my sister will kill me whenever I come
home (she hates the noise with a passion, I'm not too fond of it
eithor, which is why I like the 3055, it is reasonably quiet). Thanks.
