A useful instrument during control and reparation of audio equipment. Consists of an oscillator with a fixed frequency (1000 Hz) and adjustable output level, and amplifier with adjustable input sensitivity and output for speaker. The oscillator is connected to the equipment that is to be controlled and by means of a test probe or similar, the amplifier input is then connected to different points in the signal-chain. Any faults can easily and quickly be located in this way. The amplifier's input impedance is high, which prevents loads on the equipment that is being tested. Shielded cable is recommended for the oscillator's output and the amplifier's input.
