Re: Polk Audio PSW 110 subwoofer
I try again. Nobody can measure the voltages on the secondary of the transformer after the rectifier diodes, when the sub is running and in the ON state?

Re: Polk Audio PSW 110 subwoofer
I have part of amplifier schematic, lack the schematic of oscillator/comparator little pcb mounted vertical and seems nowhereto by found. Anyway on the schematic there are not voltage reference, i think voltages on the transformer output are too low , nobody know something about what need to be these voltages after the rectifier diodes over filter suplpy capacitors?Leave a comment:
