Controls & Indicators

ZERO ADJUST: This control is used to adjust the meter to zero after selecting the test and before connecting the transistor.

GAIN CAL: This control sets the test reference for the device under test and is adjusted to position the meter pointer to the GAIN CAL line with the transistor connected.

TRANSISTOR TYPE: The first four red pushbuttons in the top row select the test current for regular (bi-polar) transistors. The next two select either gate 1 or gate 2 for the FET test, and the last two select the mode of FET operation.

FUNCTION: The bottom row of eight black pushbuttons select the type of test to be performed on the transistor. The first is the AC power switch with a push on, push off action, indicated by a light above the On pushbutton. Buttons 2 and 3 select the polarity of the test; N for NPN transistor or N channel FET, and P for PNP transistor or P channel FET. Buttons 4 and 5 select either AC or DC test voltages. The remaining three buttons are momentary contact types, used to make the actual test on the transistor or FET.

LEAD CONNECTIONS:
– E-SOURCE: This jack and black clip lead connect to the emitter of the transistor or the source of the FET.
– B-GATE 1: This jack and yellow clip lead connect to the base of regular transistors, gate of single gate FETs, and Gate 1 of dual gate FETs.
– C-DRAIN: This jack and red clip lead connect to the collector of regular transistors and to the drain of FETs.

The TF166 allows for fast, automatic testing with pushbutton setup and a simple GOOD – ? – BAD scale for assessing transistor gain.

For FETs, the analyzer measures mutual conductance (Gm), leakage current (Ioss), and zero bias drain current (Idss). The device provides both in-circuit AC tests and out-of-circuit DC tests, ensuring safe, non-destructive testing. The controls include a zero adjust for meter calibration, a gain calibration control for setting test references, and pushbuttons for selecting transistor type, test polarity, and test voltage type.

Specifications

Refer to the PDF for details.

Controls & Indicators

Refer to the PDF for details.

Installation / Setup

The installation and setup of the Mighty Mite II Tube Tester involve several key steps. First, plug the line cord into a 110 or 120 volts AC, 60 cycle receptacle. Locate the tube in the setup booklet, which lists tubes numerically and alphabetically, and note the setup information for controls A, B, C, and D, as well as the tube socket number. Set the controls as indicated and insert the tube in the specified socket. For tubes with more than one listing, perform complete checks using each listing, but the “Short” test only needs to be done once.

Set the FUNCTION switch to CAL and adjust the meter to the CAL line on the right-hand side by using the CAL adjustment. This calibration is not needed every time but should be checked before rejecting a tube. The meter’s “zero” is about ¼ inch from the left side of the scale.

Switch the FUNCTION switch to the desired test. For a complete check, start with the SHORT TEST by setting the FUNCTION switch to SHORT TEST and switch D to the H-K position. The SHORT IND. lamp will glow if there is leakage of 120,000 ohms or less between the heater and cathode. Rotate switch D through all settings from H-K to A while watching the SHORT IND. lamp. A bright glow indicates a short or leakage, while a dim flicker does not. Normal shorts are listed in the tube setup charts and are permissible. If the short check is OK, proceed to the GRID LEAKAGE test and reset switch D as indicated in the chart.

Operation

To operate the TC114 Mighty Mite II, follow these steps:

1. Plug the line cord into a 110 or 120 volts AC, 60 cycle receptacle.
2. Locate the tube in the set-up booklet, noting the set-up information for controls A, B, C, and D, and the tube socket number.
3. Set the controls as indicated and insert the tube in the specified socket. If multiple listings are shown, perform complete checks using each listing. The “Short” test only needs to be done once.
4. Set the FUNCTION switch to CAL and adjust the meter to the CAL line on the right-hand side by using the small black adjustment marked CAL. This adjustment is not needed every time but should be checked before rejecting a tube.
5. Switch the FUNCTION switch to the desired test. For a complete check:
a. Set FUNCTION switch to SHORT TEST and switch D to H-K position.
b. The SHORT IND. lamp will glow if leakage of 120,000 ohms or less exists between heater and cathode.
c. Rotate switch D through all settings from H-K to A while in SHORT TEST position. Watch the SHORT IND. lamp for glowing, which indicates a short or leakage. Flickering or dim glow on one electrode does not indicate a short. Bright glow on both electrodes indicates a short. Normal shorts are listed in the tube set-up charts and are permissible.
d. If the short check is OK, switch FUNCTION switch to GRID LEAKAGE and reset switch D as indicated in the chart.
