The B&K Precision Dyna-Jet Tube Tester manual provides detailed instructions for setting up and operating the Model 666/606, including testing various types of tubes for shorts, leakage, grid emission, and gas. It also includes troubleshooting techniques to identify defective tubes by using sensitive tests that simulate actual operating conditions.
Manual Overview
The B&K Precision Model 666/606 Dyna-Jet Tube Tester is designed to test a wide range of tubes, including those commonly used in radio, television, and various industrial applications. It automatically checks for shorts and leakage up to one megohm, ensuring comprehensive testing by examining each element-to-element combination. The tester also performs a sensitive grid current check, detecting grid emission, gas, and grid contamination with a sensitivity of over 100 megohms. Each section of multi-section tubes is tested separately to assess cathode emission under simulated operating conditions.
For troubleshooting, the tester uses a neon lamp to indicate shorts or leakages. The grid emission and gas test circuit employs a 6BN8 d.c. amplifier, where a positive voltage drop across a 5.6 megohm resistor indicates a defective tube. This setup helps identify tubes that may cause issues in TV circuits, such as a.g.c., sync, and amplifier circuits. The manual provides detailed guidance on using these tests to ensure accurate diagnostics and efficient servicing of electronic equipment.
Quick Issues Covered
- Diagnose shorts with automatic neon lamp indicator.
- Adjust grid emission sensitivity for accurate leakage detection.
- Trace circuits using detailed schematics for troubleshooting.

Operation
The Dyna Jet Model 666/606 Tube Tester is designed to test commonly used tubes in radio and television sets, as well as many voltage regulator tubes, thyratron tubes, industrial types, and European types found in modern hi-fi equipment. It automatically checks for shorts and leakage to approximately one megohm, and tests for grid emission, gas, grid contamination, or obscure grid to cathode leakage with a sensitive grid current check. Each section of a multi-section tube is checked separately, and tubes are checked for quality under conditions simulating actual operating conditions.
For testing tubes for shorts, the tester uses a neon lamp indicator. The shorts check is automatically made when a tube is placed in the proper socket, and further checks are made by rotating switch “C” and observing the shorts light.
The quality test is a comprehensive cathode emission test under load conditions to ensure proper operation in a circuit.
The grid emission and gas test helps identify tubes that can cause trouble in TV circuits. It detects negative grid current and gas current, which can affect the bias voltage and lead to issues like clipping or overloading in TV sets. The test circuit biases the grid beyond cut-off, and any grid emission or gas current will cause a meter deflection indicating a defective tube.
