Gary, when my amp on my orignal version 600 failed, Andrew tested it on the work bench.. The main board had died... The first version of the amp was a 1 channel 600W amp... the new amps are 2 mono channel 300W amps...

As you know i wound up getting a new amp for my old 600... the new amp has a 5 year warrantee..


The op's problem could have possibly been something within his house, maybe in adequate wiring or low voltage.. Since as voltage drops current has to increase to maintain the same amount of power....

No telling....
