Manual Overview

The Sencore TC162 Tube Tester manual provides detailed instructions for setting up and troubleshooting tube tests. The device uses a series of switches (A, B, C, and D) to isolate tube pins, select filament voltage, apply load resistance, and control grid selection for testing. Before testing, technicians should set the FUNCTION switch to SHORTS and adjust the METER ZERO for a zero reading. The manual emphasizes checking for shorts by rotating the D SETUP switch and observing the shorts indicator, noting that faint flashes can be ignored. For emission testing, the FUNCTION switch is set to EMISSION, and the reading is taken from the meter’s top scale. The LIFE TEST involves pressing a slide switch to observe emission drop, indicating tube rejection if it falls into a questionable range. The GRID LEAKAGE test requires setting the FUNCTION switch to GRID LEAKAGE and checking the meter’s bottom scale, with readings in the green area being acceptable. The manual also advises checking the warm-up time of tubes to prevent issues in television receivers.

Quick Issues Covered

• Diagnose tube shorts using D SETUP switch positions.
• Calibrate meter zero before testing tubes for accuracy.
• Trace schematics for tube pin connections and voltage settings.

Controls & Indicators

A Switch: The A switch is a row of 10 slide switches that isolate the pin on the tube socket corresponding to its number when the switch is in the down position.
B Switch: The B switch selects the filament voltage to be applied to the tube under test. It should be set to the range of filament voltage that includes the voltage indicated in the setup chart.
C Switch: The C LOAD switch selects the correct applied voltage and load resistance, allowing the tube under test to be tested 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.

Installation / Setup

Operation

The operation of the TC162 Mighty Mite VII Tube Tester and TC28 Hybrider involves several steps:

1. Switch Setup:
– A Switch: Consists of 10 slide switches that isolate the corresponding pin on the tube socket when in the down position.
– B Switch: Selects the filament voltage for the tube under test. It should be set to the range that includes the voltage indicated in the setup chart.
– C Switch: The LOAD switch selects the correct applied voltage and load resistance for testing the tube at its rated current.
– D Switch: The SETUP switch selects the control grid for the emission and grid leakage test and is rotated for checking.

2. Initial Setup:
– With no tube in any socket, set the FUNCTION switch to the SHORTS position and adjust the METER ZERO for a zero indication on the meter.
– 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. Testing Procedures:
– Check Shorts: Rotate the D SETUP switch to all positions and observe the shorts indicator. The unit will indicate shorts on both electrodes if the tube is shorted or has excessive leakage. Faint flashes in the short indicator can be disregarded. Tubes marked with an asterisk (*) in the setup chart may show a normal short or leakage due to non-standard filament connections.
– Check Emission: Rotate the FUNCTION switch to the EMISSION position, return the D SETUP switch to the indicated position in the setup chart, and read the top scale on the meter. If the tube has good emission, proceed to the life test.
– Life Test: Maintain the setup for the emission test and push the LIFE TEST slide switch. If the emission reading drops into the questionable area, the tube should be rejected.
– Check Leakage: Maintain the setup for the emission test, rotate the FUNCTION switch to the GRID LEAKAGE position, and read the bottom scale on the meter. If the meter reads in the green area, the leakage is acceptable. If it reads in the questionable area, the tube may function but should be replaced to prevent future issues.

4. Additional Considerations:
– When replacing a costly horizontal output tube in a television receiver, check the horizontal oscillator tube for emission, filament sensitivity, and warm-up time to prevent future issues and maintain customer confidence.

Manual Overview

The Sencore TC28 Tube Tester manual provides detailed instructions for setting up and troubleshooting the device. The manual emphasizes the importance of using the A, B, C, and D switches correctly according to the setup chart. The A switch isolates specific pins on the tube socket, while the B switch adjusts the filament voltage. The C switch manages the applied voltage and load resistance, and the D switch is used for emission and grid leakage tests. For troubleshooting, the manual advises checking for shorts by rotating the D switch and observing the shorts indicator, with specific attention to tubes marked with an asterisk, which may show normal shorts. The emission test is performed by setting the function switch to EMISSION and reading the meter. The life test involves observing the emission drop when the LIFE TEST switch is pressed. The manual also highlights the importance of checking the horizontal oscillator tube in television receivers to prevent premature failure of the output tube. For leakage testing, the function switch is set to GRID LEAKAGE, and the meter reading is assessed to determine tube condition.

Quick Issues Covered

• Diagnose tube shorts using D SETUP switch and shorts indicator.
• Calibrate filament voltage with B switch for accurate tube testing.
• Trace circuits using schematics for grid leakage and emission tests.
