Manual Overview

The Hickok 800 Dynamic Mutual Conductance Tube Tester manual provides detailed instructions for troubleshooting, diagnostics, and calibration. The tester is equipped with an 81 lamp for overload indication and a 49 lamp to protect the bias potentiometer. If these lamps glow brightly, it indicates a potential issue, prompting a recheck of settings and a leakage test. Calibration involves adjusting the line voltage using the LINE ADJUST knob while holding down button P7 until the meter aligns with the LINE TEST mark. Selector knobs are used to set voltages to the tube’s base pins, with specific dialing numbers provided on a roll chart. Leakage or shorts are checked by rotating the leakage switch through its positions and observing the meter for indications. The manual includes a table to locate leakage between tube elements, aiding in precise diagnostics. The tester requires two rectifier tubes, an 83 and a 5Y3GT, and operates on a 110-125 volt power source.
