Note 1: Coil: L=100µH (Mitsumi C5-K3L) transistor: SANYO 2SD1628

Condenser: C=33µF (tantal condenser) Base resistor (Rb) : 1.0kΩ

Shot key barrier diode: ROHM RB491D Base resistor (Cb) : 2200pF

Note 2: The cause of oscillation is due to set wiring and capacitance changes in capacitor caused by

temperatures changes, so please take extra care in placing the wires.
