The latest piece of test gear to be put into service is the Heathkit T-4 Signal Tracer. This should be a useful piece of gear for checking receivers and other audio gear. It is basically a high gain amplifier with a speaker, 'magic eye' indicator and an RF/Audio probe. You can check for an aural signal or watch the indicator for a signal at various points in a circuit. It also has a 65V DC signal option at the probe tip for checking intermittent solder joints or other 'loose' connections.
