audio amplifier as a power generator (instruction)

[dxer_87]

corrected version of  closing right channel. should be more efficient. some of old radios were working well with mico noplis - using lower voltage ac line and most of them prefer phase to work. anyway this can give overunity. according to what i've experimented wounding a little bit of cable (same direction) on existing right channel coil can give extra kapanadze resonance.

I've decided to test Jawik and have a spare coil for right channel of amplifier. I took a wire that goes around tube in 17' crt monitor. Had taken off black insulation tape, then I started wounding a coil. It is 20mm thick after work and has inductance of 240mH. That is good minimum to work as a let's call it 'fat coil'. I have also bought 100 metres of 0.22mm2 insulated cable to wound the frog coil winding on the existing one. I think about 10-15 metres would be enough(~500turns or bit less) to achieve 35-38mm thickness, that on such diameter Tesla/Kapanadze resonance happens. It will be tuned by triangle/sawtooth generator 3,3V amplitude (i have idea to lock output by Zener) with regulated frequency on potentiometer. I will tune the volume to 80% and watch for voltage increase on the coil output, also the coil will be connected via RC (100ohm, 120nF) circuit into minus.

Hope to achieve good effect.

Wire from up to 32'CRT is fine, the coil may be up to 45mm thick. After this diameter, effect is near the same.

Greetings to all!

Here is corrected version of extra grounding. The big resistor goes into Base of course, there was a mistake in instruction. You may add capacitor 100nF or 47nF parallel to R1 to achieve better sucking energy of Earth. The 2M ohm resistors are for the sake of saving transistor if someone would put a phase instead of neutral. In your case a different resistor may be used like 1.5k ohm, not 2.2k ohm. You need to verify this in your own system.

Also corrected 'getting signal' circuit. For the safey reason of audio stage an electrolytic cap is included. Also two different mass are mentioned, that combining with extra grounding should work well .
