I got a pair of JBL L212 in which the powercompany unfortunally have blown the amplifier in the subwoofer. Everything works, but the 50Hz tone (i am living in Sweden) from the main voltage is getting through to the woofer. I think the capacitors are blown and wonder if anyone has any ideas of where i can get new ones. I have searched the net but could'nt find anything. It would be nice to use the speakers with original amplifier for the subwoofer.
