The service manual for the B&K Precision Model 700 Dyna-Quik Tube Tester provides detailed instructions for setting up and operating the device, which is capable of testing over 99% of TV tubes by measuring their dynamic mutual conductance and checking for shorts, leakage, grid emission, and gas. It also includes troubleshooting guidance, such as identifying defective tubes through sensitive tests for grid emission and gas, ensuring accurate and efficient tube testing.
Manual Overview
The B&K Model 700 Dyna-Quik Tube Tester service manual provides detailed instructions for troubleshooting, error diagnostics, calibration, and board-level guidance. The tester is designed to evaluate the dynamic mutual conductance (Gm) of TV tubes, which is crucial for assessing their amplification capabilities. It features a true transconductance bridge for accurate Gm measurement and includes tests for shorts, leakage, grid emission, and gas presence. The shorts test is sensitive to approximately 1 megohm, with visual indicators for faults. Grid emission and gas tests are critical for identifying tubes that may cause issues in TV circuits, using a sensitive circuit to detect negative grid current. Calibration involves ensuring the correct AC signal voltage is applied for accurate Gm readings. The manual emphasizes the importance of testing each section of dual-section tubes separately for balance, which is essential for push-pull circuits. The tester is adaptable to new tube types, ensuring longevity and relevance in evolving technological environments.
Quick Issues Covered
- Diagnose tube shorts and leakage up to 1 megohm sensitivity.
- Calibrate mutual conductance using a sensitive bridge circuit.
- Trace circuits with detailed schematics for grid emission tests.
Overview
The Dyna-Quik Model 700 Tube Tester is designed to test more than 99% of TV tubes quickly and accurately. It measures the dynamic mutual conductance (Gm) of tubes using a transconductance bridge, checks for shorts and leakage, and performs sensitive grid current checks. The device tests each section of dual-section tubes separately and is equipped to handle new tube types, making it adaptable to future developments.
