High Voltage Audio Experiment

Just for Fun,
I Used a transformer to step up an Audio Voltage Signal from 20Vpp to approx 160 Vpp
to see if I could receive the Di-Electric Signal via loosely capacitively coupled cabling and amplify using the Mic Input on an Audio Amplifier.

(The Transformer tested as having a self resonance of approx 9 KHz when configured as a Step Up Transformer.)
