trying to keep up with you, but i am still at this first opamp circuit using a TL084 instead, powered from 2 12V batteries (so +12v and -12V).
Nice hissing sound from the earplug / MOSFET amplifier, but nothing else.
There is 15V directly across the diode 1n34 (25V total across the 2 resistors (1M each) and the diode).
At least the radio stations are gone (also the pilot/control like signal), so there could be no mistake there.
