Coils will work fine with a spark gap transmitter.  Take a look at my tests on the Don Smith resonance thread maybe 3-8 pages back or so.  There are also pictures of my set up.

Thanks for info. I have found elsewhere how to find hv coil ground by "testing" for arc. The other coil connections do not match yours. I do not even have a loop between pins you have found handy probable different tranz. Have it up and running 12DC @ 800mA.
I am using TIP121 (the only tranz I had and it is some kind of "double" tranz) and 4.7nF cap. 1" spark tops so far. Did not even try to tune it. Probably 13005 would be better or different cap. Gets pretty warm after a minute or two of running.

Minde,

Glad you got it running. 1 inch arc at 12v sounds good.

Its taking quite a draw for 12v, you could try changing your transistor base bias resistors for more off time, maybe increase the resistance that ties the base to positive rail.

Can you convert this output using cap to some more or less stable 200-400khz spark transmitter? I dont care much about voltage as long as I have some 2kv @ 400khz or whatever would be possible. I think too much of a small cap would not be able to smooth it out anymore. What do you think is limit?

A spark gap transmitters tuned frequency is determined by the fundamental resonance of the LC tank circuit after the gap.

You should be able to get between low kHz and many tens of MHz depending on L and C (equation below for f).

A spark gap transmitter does not produce a steady RF signal, each time the gap fires you get a short burst of oscillation that rings down, then the cap recharges and fires again and so it repeats.

You limit the working voltage by using a smaller gap, this also increases refire rate.

Spark refire rate is usually below or around 1kHz.
