Hi Ronv,
I built the circuit. I used a Capacitor 103 instead of 0.006U. Is this ok.
The test Battery pack is 10.5V. The output at LM339 shows 9V App. If I remove the LM139 the voltage at the +input pin, with no signal is 20mV. If I add a typical signal through the Coil, it show 200+mV.
I have access to an Oscilloscope 1 day/week. If you wish to help me troubleshoot the circuit.
