What if there isn't enough current? I was planning on powering it with a
very small high voltage DC supply. I saw on one website a guy built a
handheld herf where the entire appratus fitted inside the magnetron casing
and was powered by 4 D batteries, it of course was pulsed by charging up a
small array of caps at 7000 volts, but it was safe enough for him to hold it
during operation and place his hand right above the transmitter.
