The sound of water running into a bathtub is like white noise.  A 
sound-effects man could probably simulate it in different ways.  The 
sound I heard was trickling or dripping.  It was familiar in real life, 
but I hadn't known it could come over a radio so clearly.

We're talking about crossing over from positive to negative in a 
push-pull amplifier.  A feedback resistor sounds like the way to 
mitigate it.
