The manual for the B&K Precision Dyna-Jet Tube Tester Model 666/606 provides detailed instructions on setting up and operating the device, which is designed to test various types of tubes used in radio and television sets, including voltage regulator and thyratron tubes. It also includes troubleshooting techniques for detecting shorts, leakage, grid emission, and gas issues in tubes, ensuring accurate and dependable testing results.
Manual Overview
The B&K Precision Model 666/606 Dyna-Jet Tube Tester manual provides detailed instructions for testing various types of tubes used in radio, television, and modern hi-fi equipment. The tester automatically checks for shorts and leakage, detecting issues down to approximately one megohm. It also performs sensitive grid current checks to identify grid emission, gas, and grid contamination, revealing currents as low as 2-3 microamperes. Each section of multi-section tubes is tested separately, and the tester evaluates cathode emission under simulated operating conditions to ensure tube quality.
For troubleshooting, the shorts check is conducted automatically when a tube is inserted, using a neon lamp indicator. The grid emission and gas tests are crucial for identifying tubes that may cause issues in TV circuits, such as a.g.c., sync, and amplifier circuits. The manual explains the theory behind grid emission and gas current, illustrating how these can lead to operational problems like signal clipping. The tester uses a specific circuit to detect these issues, providing a clear indication when a tube is defective and needs replacement.
Quick Issues Covered
- Diagnoses shorts and leakages with neon lamp indicator.
- Calibrates grid emission sensitivity over 100 megohms.
- Includes schematics for circuit tracing and 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 each tube for shorts and leakage, revealing issues such as grid emission, gas, grid contamination, or grid to cathode leakage with high sensitivity. Each section of a multi-section tube is tested separately for quality, simulating actual operating conditions. The shorts check is conducted automatically when a tube is placed in the socket, using a neon lamp indicator. The quality test involves a comprehensive cathode emission test. The grid emission and gas test is particularly useful in TV servicing to identify tubes that may cause issues in circuits. The test circuit for grid emission and gas involves applying normal plate to grid voltage with the grid biased beyond cut-off, using a 5.6 megohm resistor and a 6BN8 d.c. amplifier to detect defects.
