My mailer doesn't know your host. How 'bout a low freq audio (two xstr) osc that drives a small 8 ohm to 1-5K ohm speaker xfmr? Actually, with one cmos gate ic, you can get a gated osc that is freq and gate time adjustable. Then go through a couple of xstrs to the xfmr. After you have found the right combination of on-time and freq, hardwire a simple xstr circuit that gives that best values. Protect the driver stuff with diodes, also across the battery to keep the HV out of it. Try to power this thing w/9volt batteries, its gotta be less expensive. Ah, the brain IS alive today...another idea for ya. You might want to measure what voltages are generated in battery powered flourscent lanterns. Those guys must have start up pulses that are mean. I know they have tiny transformers in them. Maybe the circuit from a photographic "strobe" (flash). Did this give ya any ideas? Sometimes a devious mind IS useful! Bill WB6RZG
