Re: Spark Gap Oscillator Efficiency



In the past, spark-gap oscillators have been widely used as sources of
power for induction heater and diathermy.  I remember very well the
induction heater used in the first transistor/diode manufacturing lab at
Hughes Aircraft, back in the very early '50's.  It used a spark gap, and
caused unbelievable QRM for all of the rest of us.  But, it DID work!
