What do bad caps sound like?

When they went out in my subwoofer amp they made the driver just go pfft pffft blffft pfft pfft. Pppppppb pppppb. BTW- I'm not kidding. Really. REALLY! You should have heard me trying to explain it to Albert at VSA.

You could also SEE that the caps had gone out as the tops were flat but when they went out they were domed.

You will usually get a hum that may increase while your amp is playing music and the caps discharge. Bad power supply caps can no longer block ripple current.
