Operation

The TF26 Touch Tone Cricket is designed to test transistors or FETs without needing to know their basing, polarity, or type. The device uses a computer logic circuit to determine if the transistor or FET will invert a square wave input. It features six pushbuttons and a polarity switch to provide all possible combinations of connections. To perform a gain test, the user should:

1. Remove power from the equipment containing the device being tested and discharge all power supply filter capacitors.
2. Turn on the TF26 and connect the test leads to the device’s leads. The basing of the transistor does not need to be determined as the touch tone circuit will handle it. If the device is a plug-in, the front panel mounted transistor socket can be used.
3. Select the GAIN test and press each of the six test buttons in turn. If the Cricket does not chirp and indicate in the good area of the meter, select the opposite polarity and press the test buttons again. If the Cricket still doesn’t chirp, the device is probably bad. It is advisable to retest the “bad” transistor after removing it from the circuit to isolate rare instances where a good transistor tests bad in-circuit.

In some cases, a good transistor may test bad in-circuit, particularly if the circuit’s base to collector resistance is less than 100 ohms or if large electrolytic capacitors are connected directly between the base or collector leads and ground. If a transistor tests bad in-circuit and good out-of-circuit, it may indicate other circuit problems, such as shorted foils on the board or large resistors connected to the transistor that have changed value or become shorted.

Troubleshooting & Error Codes

Refer to the PDF for details.

Safety & Warnings

When testing electronic equipment, there is always a danger present. Unexpected high voltages can be present at unusual locations in defective equipment. The technician should become familiar with the device that he is working on and observe the following precautions:

1. When making test lead connections to high voltage points, remove the power. If this cannot be done, be sure to avoid contact with other equipment or metal objects. Place one hand in your pocket, as a safety precaution and stand on an insulated floor to reduce the possibility of shock.

Operation

Set controls A, B, C, and D according to the set-up chart and insert the tube in the socket indicated in the chart. Use the cap lead if the tube has a top cap connection. On Mighty Mites up to TC142, set the FUNCTION switch to the CAL position and adjust the CAL control so that the meter reads full scale (marked CAL). On the TC154 Mighty Mite, press the SHORTS function pushbutton, and adjust the METER ZERO control to position the meter pointer to the extreme left-hand edge of the meter scale. Switch to the SHORT TEST or SHORTS function and rotate the D switch through all positions. The SHORT IND. or SHORTS light will glow if a tube is shorted or has excessive leakage. Tubes marked with an asterisk in the set-up chart have internal connections that will show up as a short on the D switch positions indicated. The H-K setting is for heater to cathode leakage (or short) test. Any tube that shows a short not indicated as normal should be rejected immediately, as possible damage to the Mighty Mite transformer will result from checking a shorted tube for emission. Switch to the EMISSION position, and return the D switch to the setting indicated in the set-up book. Read the top BAD ? GOOD scale on the meter, and reject any tube that reads in the BAD area of the meter scale. Occasionally, you will encounter a tube which has a FILAMENT SENSITIVE cathode. This tube will test good in your Mighty Mite when operated at the rated filament voltage but may not work in circuit. This is especially true of tubes in series string receivers. If the line voltage is low, or one or more of the tubes in the series string is dropping a higher than normal voltage, the emission level of the cathode drops and the circuit ceases to function. The test you should make on every tube to determine if it has a FILAMENT SENSITIVE cathode is a LIFE TEST. When you test the tube for emission and it reads in the GOOD area of the meter, switch the FILAMENT (A) switch DOWN one step (i.e., 6V to 4-5V). The meter indication of a good tube will not change, or change only slightly, but a filament sensitive tube will drop off quickly to the (?) or BAD area. If the meter reading falls off but still remains in the GOOD area, the tube is still acceptable, but once the meter reading hits the question mark (?) or BAD area, this tube should be replaced. You should run this quick LIFE TEST on all tubes you check. This will give you double insurance that the tube will work in the circuit. Switch to the GRID LEAKAGE function, and read the bottom GOOD ? BAD meter scale. Reject any tube that reads up into the BAD area of the meter. When replacing a costly horizontal output tube in a television receiver, it is a good idea to check the horizontal oscillator tube for emission, filament sensitive cathode, and for warm-up time. If the horizontal oscillator tube is slower in warming up due to a weak cathode or filament sensitive cathode, the output tube will draw heavy current and its life will be shortened considerably. Checking the warm-up time of the oscillator tube and making sure that it is as fast or faster than the output tube can reduce the chance of a call back later for the same trouble and keep your customer’s confidence high in your service ability.
