12V dc pulse generator for Tesla like circuit

[Mr Ed]

Hi,
Does anybody know where I could purchase a 12V dc pulse generator for a tesla like circuit? The specs are as follows:
Input: 12V dc
Output: 200 – 300 V pulsed dc at 30 – 80Khz (Modifiable)
10 – 20ma

Alternatively a schematic which is not too complicated so I can build it myself.

Do you mean 2000-3000v?

Nope. 200 - 300V

If the adjustment does not have to be too accurate you can use 555.

Control the transistor with the timer and use it to drive isolation transformer or whatever you want to use for producing that 200-300volts. You probably need current limiter circuitry also.

If you are making Tesla style non-linear circuitry, it is usually easier to use spark gap style designs instead of solid state, especially if you want to achieve resonance conditions in easiest way.

You might also find something at http://highvoltageshop.com/ or maybe http://amazing1.com/

I would suggest looking at Geiger counter power circuits such as this where he uses a CD4047:
