The manual for the Sencore TC162 Mighty Mite VII Tube Tester provides detailed instructions on setting up and operating the device, including the use of various switches to test tube emissions, shorts, and grid leakage. It also includes troubleshooting tips, such as checking for filament sensitivity and warm-up time to ensure proper tube function and longevity.
Manual Overview
The Sencore TC162 Mighty Mite VII Tube Tester manual provides detailed instructions for setting up and troubleshooting tube and transistor tests. The manual outlines the use of various switches: the A switch isolates specific pins on the tube socket, the B switch selects the filament voltage, the C switch adjusts the applied voltage and load resistance, and the D switch is used for emission and grid leakage tests. For troubleshooting, the manual advises setting the FUNCTION switch to SHORTS and adjusting the METER ZERO before testing. It describes how to check for shorts by rotating the D switch and observing the shorts indicator. For emission tests, the FUNCTION switch is set to EMISSION, and the meter reading is checked. The LIFE TEST involves observing the emission reading drop when the LIFE TEST switch is engaged. Grid leakage is tested by setting the FUNCTION switch to GRID LEAKAGE and reading the meter’s bottom scale. The manual emphasizes the importance of checking specific tubes for emission and leakage to prevent future malfunctions.
Quick Issues Covered
- Diagnose power-up failures using setup chart for correct switch settings.
- Identify tube shorts with D SETUP switch rotation for accurate diagnostics.
- Use schematics for circuit tracing and troubleshooting complex tube issues.

Controls & Indicators
The front-panel controls/indicators for the TC162 Mighty Mite VII Tube Tester and Tc28 Hybrider Tube & Transistor Tester include:
– A Switch: A row of 10 slide switches that isolate the pin on the tube socket corresponding to its number when in the down position.
– B Switch: Selects the filament voltage to be applied to the tube under test.
– C Switch: The C LOAD switch selects the correct applied voltage and load resistance for testing the tube at its rated current.
– D Switch: The D SETUP switch selects the control grid of the tube under test for the emission and grid leakage test and is rotated to check shorts.
Installation / Setup
The source provides detailed instructions for setting up and operating the TC162 Mighty Mite VII Tube Tester and Tc28 Hybrider Tub & Transistor Tester. It includes information on the use of various switches (A, B, C, D) for isolating tube socket pins, selecting filament voltage, applied voltage, load resistance, and control grid selection for tests. The setup involves adjusting the FUNCTION switch to the SHORTS position without a tube in the socket and setting the METER ZERO. Tubes are inserted according to a setup chart, and tests for shorts, emission, life, and leakage are conducted with specific instructions for each. There are no explicit mentions of wiring, clearances, or calibration prerequisites in the provided source.
Operation
The operation of the TC162 Mighty Mite VII Tube Tester and Tc28 Hybrider Tube & Transistor Tester involves several steps:
1. Set the FUNCTION switch to the SHORTS position without any tube in the socket and adjust the METER ZERO for a zero indication on the meter.
2. Set the A, B, C, and D switches according to the setup chart and insert the tube in the indicated socket. Use the cap lead if the tube has a top cap.
3. To check for shorts, rotate the D SETUP switch to all positions and observe the shorts indicator. Disregard faint flashes. Tubes marked with an asterisk (*) may show a normal short or leakage due to non-standard filament connections.
4. For emission testing, rotate the FUNCTION SWITCH to the EMISSION position, return the D SETUP switch to the indicated position, and read the top scale on the meter. Perform a life test if the tube has good emission.
5. The life test involves retaining the emission test setup and pushing the LIFE TEST slide switch. A filament-sensitive tube will show a drop in emission reading. If it drops into the questionable area, the tube should be rejected.
6. When replacing costly horizontal output tubes in TVs, check the horizontal oscillator tube for emission, filament sensitivity, and warm-up time to prevent future issues.
7. For leakage testing, retain the emission test setup, rotate the FUNCTION switch to the GRID LEAKAGE position, and read the bottom scale on the meter. A reading in the green area indicates acceptable leakage, while a reading in the questionable area suggests the tube should be replaced to avoid future problems.

Basic Usage and Operation Tips
Before testing, ensure the device is properly connected to the tube socket and powered on. Use the provided charts to identify the correct tube type and reference values. Carefully insert the tube into the tester, avoiding excessive force. Follow the manual’s step-by-step instructions to select the appropriate test settings. Always allow the tube to warm up to operating temperature before taking measurements for accurate results. Record readings systematically to track tube condition over time.
Troubleshooting and Maintenance Notes
If the device fails to power on, check the power supply and fuse integrity. Inconsistent or erratic readings may indicate poor tube contact or dirty sockets—clean contacts regularly with appropriate cleaners. Periodically inspect cables and connectors for wear or damage.
