[dorkbotnyc-blabber] mono powered speakers

No, this should not happen from cutting one speaker off.  However, CD
walkman output jacks take a lot of abuse.  Is the whole rig absolutely
still when you hear this noise?  It's possible that some sort of
wiggling connector somewhere (most likely where the speakers plug into
the jack) is the culprit. Is this like loud all-consuming noise, or
little background interference type noise?
