Acceptable ohm reading for a good current relay. One type of starting relay used on fractional-horsepower compressors is the current relay. This type of starting relay uses the initial high inrush ...
This mini audio compressor circuit use only one active component T1. The audio signal goes thru C1, R1, D1, C2, R3. Still a part of audio signal charge the D3/D4 detector and creates a control voltage ...
