  • Notes
  • Model TS-3 is an a-c signal tracing Stethoscope. The 1" diameter aluminum probe contains a miniature tube in a detector-amplifier isolating circuit, while the larger case houses 3 more tubes, including a power output which drives the 5" PM speaker for audible signal tracing. An a-c voltmeter may be connected to front panel jacks which terminate VTVM and output meter circuits, while earphone jacks are also provided for extremely sensitive work. Model TS-2 is a simitarly constructed Stethoscope for portable battery operation.

    Note that the schematic is for a model TS-3A.  The differences between the TS-3 and TS-3A are unknown.
