    I'm just tracing the circuit. The PSU delivers about 20mA. The key to performance with these switching HT supplies it have a good 12v supply, in the region of 3.5A or 4A. I find a small laptop supply works well. You're effectively rapidly shorting an inductor across the supply and the collapsing field generates the HT. So you need something with good peak loading characteristics.

      Here's the schematic. I'll get some sound clips recorded when I get chance and get take some measurements of the inductor.
