Hi,I bought a dt707,from the u.s ,a while back,it arrived with one end of the case broken, in the confusion I forgot and used an english mains lead ,giving it 240v.Now,when I try play music on it,it only comes through the mid/tweeters.The woofers just give out a electrical hum,which isn't altered when I adjust the volume.I'm just courrious to know what component I would have blown?
Thanks in advance.

Hi Jack, It's really hard to say. I would guess you would have some shorted or open capacitors, any type of voltage regulator circuits may be open and the main amplifier circuits could be blown. The first thing would be to check the main powersupply capacitors.

Hi Eric,thanks for the info.
Jack.
