AlexIT Posted September 23, 2021 Share Posted September 23, 2021 Hi! I have a problem with an amplifier of SVS PB 12, more precisely with the power source BASH. Between the terminals CD + CD- without signal and 0% at volume I have a voltage of approx. 12v, then when I turn the potentiometer to maximum I have a maximum of 20v. The amplifier is heard but distorted because have low voltage. I checked everything with the oscilloscope the PWM signal on the mosfet is like a spike not square. The BASH module is INDIGO 660047 REV: 3 (checked all the parts except UC 3842 which I think would be the problem). Any answer or idea is welcome. Thank you very much.
