Recording Level Meter Circuit

The circuit shows a two—stage voltage amplifier driving a recording level meter. The AC signal input is amplified, rectified, and the resultant DC voltage shown on the meter. The circuit can be used with a tape recorder or audio mixer and should be fed from a point early in the pre-amp. Current consumption in a […]

Simple Transistor Tester Circuit

The circuit used in making simple Transistor Tester Combo-2 has only one IC. This IC performs the following process as mentioned below: Test Process1: Position the transistor to the three circuit terminals of Circuit 1 (located either below of left of the terminal). Once pointed, the red LED can then identify the PNP transistor base. This […]
