Making TV Pattern Generator with ZNA234E This Circuit uses the ZNA234E IC which makes available all the waveforms necessary to produce the crosshatch, test patterns on a television screen. The composite video output can be injected directly into the video input of a receiver or used to drive a modulator for connection to the aerial […]

1500W Power Amplifier Circuit Diagram 1500W Power Amplifier Circuit Diagram This is a very high 1500W power amplifier circuit diagram by Rod Elliott. The circuit is built using 10 pairs of power transistor MJ15024 and MJ15025 (or MJ21193/MJ21194), then it will use 20 pieces of power transistor for final amplification.With very high power audio output, […]
