Question about Zapco Reference 750 Car Audio Amplifier
So I go to turn on the car and I hear pop pop pop pop. All 8 of the high speed switchers on the amp popped. I have replaced them and now the amp fault light turns on, then off, then off, then off. Any idea what else is wrong. Or better yet, schematics?
If the amp uses TIP35Cs and TIP36Cs, those will be the output transistors. Measure the resistance between legs 2 and 3 for each of the output transistors. Do any read near 0 ohms?
