Hello guys,

After a nasty thunder storm my UCD180sd modules stopped working (they were not powered up but plugged into the wall). When powered up they produce no sound, just silent....


I suspect possibly the input NE5532 might need changing, but it has bjt input transistors and not fets, so im not sure if I should change it or not.

Possibly the output fets need changing?...


Any clues as to what parts my have been damaged?
