Whadda WSMI7000 (Velleman K7000) - Signal Tracer/Injector Electronic Kit
This Signal Tracer/Injector SELF-ASSEMBLY electronic kit has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, ...) so as to detect the fault.
In this way problems can be traced more easily. The signal tracer may also be used as a simple monitor or amplifier.
