Re: Infinity PS-12 Powered Subwoofer Fired Amplifier

Got my PS-12 fixed too! Sub was humming while sitting at idle (no sound). Hum went away when I replaced the C72 capacitor.

Also the sub was making chirping noises. Noticed the light in the back flashing frequently between green and red. Could also hear internal circuitry noises (if I get up close to it), as if circuits were being activated and disabled quickly, on the order of about six times each second. Replaced the C2, C37, and C65 capacitors and all of those noises went away.

Big thanks for all the...
