How to Make Electronic Circuits to drive the rats, mosquitoes and other animals

This circuit functions with inaudible (ultrasonic) sound. Frequency to 20 kHz sound was heard by humans. The sound frequencies above 20 kHz is called ultrasonic sound. Described a series of produce (emit) ultrasonic sound frequencies between 40 and 50 kHz. Like the remote control system is also cirucit consists of a mini transmitter and receiver […]

Modified Electronics circuit power supplay

Further adjustments include a rectified and filtered heater supply to the triodes eliminating AC hum coupled to the signal path via parasitic wiring capacitances. A power transformer with a 350V-0-350V secondary supply an increased voltage supply to the output section with is then stepped down to the 5F6-A’s voltage supplies to the phase splitter, cathode […]
