My subwoofer picks up. Mobile phones, radar pulses, clicks and bangs on the
mains and occasionally short wave radio.


The very short speaker wires from amp to speaker in the box appear to be the
culprits for the higher frequencies, and the input leads the way in for the
rest, except
The mains borne crap.

It has a three core mains lead of the iec variety, but its only been doing
these things since it had a new bridge rectifier fitted a while back. I am
suspicious that some capacitors may have been damaged when the bridge went
down, but I'd have thought this would just result in hum.

The amp is built on pcbs maounted on the heatsink which effectively forms
the back of the cabinet beside the port.

Any ideas?
