What I meant by 300 and 500 Hz/1/60th sec is every 1/60 of a second there will be 300 to 500 pulses into C1. In other words, 18,000 to 30,000 pulses per second. And yes, my mistake... Current lags Voltage in an Inductor! :confused: The circuit is proprietary!
Regretably, I haven't had the time to draw the circuit. However, mfb has the answer I was looking for!
Ans: Transistors of all types usually come in two sorts - one (T1) gets switched ON with high input voltage and the other (T2) gets switched OFF. This appears to be what I'm looking for...
I'm trying to put together a diagram with Yenka (electronics app.) It might be a day or 2-3 (or more) before I can upload it.
Thanks for your patience.

My goal is to use a single signal to do two things at the same time...when DC signal is applied turn transistor1 off and turn transistor2 on. Then when signal is not applied transistor1 returns to on and transistor2 returns to off. Frequency will be no more than 60Hz.
What would this circuit...
