This useful instrument is practically in perfect physical and operating condition and should serve you well for many years to come!
Description:This instrument is used to trace both audio and RF signals through a circuit to help locate faults.The probe is switchable to select either audio or RF.When RF is selected, a diode detector and filt...er is placed in the circuit.The audio or detected signal is passed to a 2-stage tube amplifier with adjustable gain.The amplified signal is then passed to a driver stage to power the internal speaker.A green "eye tube" gives a visual indication of the signal strength or audio level.The speaker and its audio output transformer can also be used independently of the signal tracer to diagnose vacuum tube audio amplifiers.
