Simple inverter for EL wire development test.
Not provided.
I'd recommend a suitable value of resistor from Q2 base to emitter. This will divert Q1 leakage current and also discharge Q2 internal capacitance. Hope this is helpful, mike. |

It is good idea for hi frequency. This puppy is only 1kHz :) Now after 70 years of transistor invention even Chinese transistors have very small leakage. :) |

Thanks Alex. Showing my age! If Q2 turns off really slowly then you won't need a catch diode across XFMR1 primary. :) |

Mike, I feel the same urge to add extra components to make design more tidy and classic. :) Bit according to Occam principle we have to keep it minimum. :) This is supposed to be almost sinusoidal resonance oscillator witj EL wire capacity and C2 feedback limiter. Thus no diode is needed to protects from voltage spikes. :) By the way, I looked ot you site and like it. Thanks! |
