You need only a small transformer wit 2*12V output, maybe 100mA, the transistors are starndard NPN stuff in TO-92, all diodes also 1n4148, 2 zener diodes 6.8V. I didn`t note which LED is for NPN and PNP, but you can try out with a known transi. The extra switches are only neede, if you want to test also FETs ands Triacs. Else they can be left away.

Connect leg 1 to leg 3 with an alligator clip lead and place the probes across legs 2 and 3. With the meter in diode-check mode, you should have a reading of approximately 0.5-0.9 with the probes one way and no reading (OL) with the probes reversed.

With the signal feeding into the tank output, i had the bright idea to feed the audio signal from the tank input,(output from preamp) back into the main instrument input, to see if the reverb input circuit was working. The amp promptly oscillated, and blew a fuse. It will blow a fuse immediately if the output transistors are connected.

Now, connect the leads to both the negative terminals. If the multimeter shows 1 as a reading then the transistor is just fine. And if this is not the case then the multimeter produces a buzzing sound and shows 000 as a reading ,and the transistor is just too bad for use as shown in the video. Ask Question.

Press the 'Test' button, note the readings, and mark the transistor just tested (so you can correlate the device with its measured characteristics). Repeat the test with the other devices you have, reversing the polarity (SW3) if required - but do not adjust the pot - leave it exactly where it was for the first transistor. Bear in mind that the current in subsequent transistors could vary by …

If it is reading a short collector to emitter in circuit then the drivers transistors are suspect. Leave the outputs clean out and fire it up and take voltages. If you read low B-E and the rest of the amp is OK you should get low offset and no drop across the emitter resistors.
