My trusty old tesla coil has died after 40 years of faithful
service.  It was a vacuum tube version using a push-pull
oscillator circuit working in the range of 150 KHz.  In its
best days it was capable of a 3 to 4" arc and would light a
neon or fluorescent lamp at a distance of 4'.  The tubes used
were #10 which were last manufactured during WWII as the VT-25.
The coil measures 30" in length and 3" in diameter close-wound
with #30 wire.  I don't remember the number of turns on the
coil, I can only tell you that it took two of us an entire day to
wind that coil by hand.

Now I am trying to duplicate its display using solid state
components and I am unable to find any diagram or solid-state
device which will come anywhere near the performance of the old
coil.  If you know of any source of circuits that might do the
job would you please respond to this posting.

Thanks for any help you can provide on this question.
