The manual for the Bk precision 1962 covers the setup and operation of the Model 650 Dyna-Quik tube tester, including instructions on how to set the Heater switch, insert the tube in the correct socket, and adjust the Sensitivity control. It also provides troubleshooting guidance, indicating that tubes are defective if the Shorts light glows or if the meter shows a reading in the reject area of the grid emission scale, and explains how to perform a life test on each tube section.

Manual Overview

The BK Precision 1962 manual provides detailed instructions for troubleshooting, diagnostics, calibration, and board-level adjustments for technicians. The troubleshooting flow involves setting the heater switch based on the tube type, followed by inserting the tube into the appropriate socket or using an adaptor. Sensitivity control settings are crucial for obtaining accurate readings. The function switch is used to test for shorts and grid emissions, with defective tubes indicated by a glowing shorts light or a meter reading in the reject area. Multiple-section tubes require testing each section separately using the Test 1, Test 2, and Test 3 positions on the function switch. Calibration and adjustments are guided by sensitivity settings, which provide only good/bad results unless the original 1960 data chart is used for true mutual conductance results. The manual emphasizes the importance of using the correct panel and chart for specific tube types, with additional information available at the rear of the chart for specific models.

Quick Issues Covered

• Diagnose power-up failures with step-by-step troubleshooting guide.
• Calibrate mutual conductance using sensitivity control settings.
• Identify defective tubes via short-grid emission test procedure.

Overview

The product is a Tube Selector, specifically the Model 650 Dyna-Quik. The manual provides instructions on how to use the device to test tubes. It covers setting the Heater switch, positioning switches according to a chart, inserting tubes into sockets or using adaptors, setting the Sensitivity control, and using the Function switch to test for defects and mutual conductance. It also includes instructions for testing multiple section tubes and performing life tests on each section.

Controls & Indicators

The front-panel controls and indicators for the Model 650 DYNA-QUIK include:

1. Heater switch: Set according to the type of tube being tested.
2. Function switch: Used to select different test positions such as Short-Grid Emission, Test 1, Test 2, and Test 3.
3. Sensitivity control: Adjusted to set the sensitivity for testing.
4. Shorts light: Indicates if a tube is defective during the Short-Grid Emission test.
5. Meter: Displays readings on various scales, including the reject area of the grid emission scale and the Good-Bad scale for mutual conductance.
6. On-Off switch: Used to perform a life test on each section of a multiple-section tube.

Installation / Setup

Refer to the PDF for details.

Operation

1. Look up the tube type on the panel or in the tube index and set the Heater switch accordingly.
2. If the tube is to be tested in the 610 panel, set the switches to the positions indicated on the chart.
3. Insert the tube into the proper socket or use the adaptor as indicated.
4. Set the Sensitivity control.
5. In the Short-Grid Emission position of the Function switch, tubes are defective if the Shorts light glows or if the meter indicates a reading in the reject area of the grid emission scale.
6. Advance the function switch to Test 1 and read the Test for mutual conductance on the Good-Bad scale.
7. If the tube is a multiple section tube (e.g., 6ATS6 triode-diode), the second section is tested in Test 2, and the third section in Test 3 position of the Function switch.
8. A life test can be made on each section by pushing the On-Off switch to the life test position.
