Hi all, here is a very efficient oscillator I've been testing.
It uses a standard 18 gauge 100 foot roll of speaker wire.
The circuit components, like the non-polarized capacitor and the resistors need to
be tuned, to observe when the circuit increases output, while input watts decrease, then you
will know you are close to a resonant point.
I had to increase the input voltage, just to get into the proper frequency range, 12 volts was not enough.
All comments welcome.
peace love light
