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

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.

Bk-precision-650 Tubes Selector Overview
The Bk-precision-650 Tubes Selector is a specialized electronic testing device designed to accurately identify and evaluate vacuum tubes. Primarily used by technicians and hobbyists, this instrument helps determine the condition and type of tubes, ensuring optimal performance in audio equipment, radios, and other vintage electronics. Its precise measurement capabilities make it an essential tool for maintaining and restoring tube-based devices.
Main Features and Specifications
- Compatible with a wide range of vacuum tube types
- Easy-to-read analog meter display for quick results
- Compact and durable design suitable for workshop use
- Simple socket interface for fast tube insertion and removal
- Accurate tube condition testing including emission and shorts
- Operates on standard AC power supply
- Model: -650- by Bk-precision
Basic Usage and Operation Tips
To use the Bk-precision-650 Tubes Selector, first ensure the device is connected to a stable power source. Insert the vacuum tube firmly into the appropriate socket, matching the tube type as indicated in the manual. Observe the meter reading to assess the tube’s condition—higher meter deflection typically indicates better emission. Always allow the device a few seconds to stabilize before taking a reading. For best results, test tubes at room temperature and handle tubes carefully to avoid damage.
Troubleshooting and Maintenance
If the meter does not respond or shows erratic readings, check the power connection and ensure the tube is properly seated. Clean the tube pins and socket contacts regularly to maintain good electrical connection. Avoid using the selector in dusty or humid environments to prevent internal corrosion. If the device requires calibration or repair, consult a qualified technician or refer to the service section of the manual.
Safety Reminder
Always disconnect the Bk-precision-650 Tubes Selector from the power supply before inserting or removing tubes. Handle vacuum tubes with care, as they can become hot during operation and are fragile. Avoid touching the glass envelope with bare hands to prevent oils from causing damage. Follow all safety instructions provided in the manual to ensure safe and reliable use of the device.
