The Model 960 Transistor Radio Analyst manual covers the setup and operation of the device, detailing its features such as a signal generator, a built-in transistor tester, and a metered power supply for testing and aligning radio components. It also provides troubleshooting guidance, including methods for measuring transistor operating voltages and diagnosing common issues in transistor radios.
Manual Overview
The Model 960 Transistor Radio Analyst is a versatile tool designed for servicing transistor radios. It features a signal generator that tunes from 250 kHz to 2.2 MHz, with variable output for signal injection or RF/IF alignment. The generator can operate with an internal 2 kHz tone or remain unmodulated. The device includes a 2000 Hz signal for audio section testing and a built-in “In Circuit” transistor tester for diagnosing faulty stages using the Dyna Trace probe. The metered power supply ranges from 0-15 mA and 0-150 mA, providing voltages from 0 to 12 volts in 1.4-volt steps, suitable for radios with tapped power supplies. The VTVM section offers a two-range DC voltmeter and an ohmmeter with a 1K ohm center scale. It also provides an “out of circuit” transistor test for leakage and beta, with a PNP-NPN switch for polarity. The manual emphasizes the importance of current readings for troubleshooting, suggesting that deviations from normal current draw indicate defects. The selector switch controls the device’s functions, and power supply jacks facilitate connections to radios under test.
Quick Issues Covered
- Diagnose power-up failures with metered power supply, 0-12V range.
- Calibrate RF-IF alignment using built-in signal generator, 250kHz-2.2MHz.
- Trace circuits using In-Circuit transistor tester for dead stage localization.
