Or maybe, does anyone know how to build one?  I have an older HP 8021B that puts out a nice square wave in the 5 to 100 kHz range, and an NPN mosfet or two.   The sig gen won't directly drive the mosfet, not enough power.  Can I use an LM386 audio chip?  What other components should I add to get a nice high power pulse DC signal to my concentric tube cell?

Any guidance or comments appreciated.

Thanks

Look up some driver circuits for mosfets.  You can drive them with a transistor and drive the transistor with your generator.  Like amplifying the generator output.
It is the men of insight and the men of unobstructed vision of every generation who are able to lead us through the quagmire of a in-a-rut thinking. It is the men of imagination who are able to see relationships which escape the casual observer. It remains for the men of intuition to seek answers while others avoid even the question.
