This unit has some weird schematic oddities that are slightly perplexing. Is the first transistor acting like a regulator? Why is there a diode in series with the shunt switch instead of a resistor to prevent contact damage? You can hear the pop from the switch as it shunts the capacitor. The unit seems to work in the sense that it has a violet LED and electrified grid, but the circuitry is slightly weird.
