well, here's a little off-topc, but related tid-bit...... there is this electrical company called ricky stator (and it's related ricks stator).... well, they used to make some decent high output stators for atv's, buikes, sno-go's, etc...... some years back, they totally went to crap. about the same doa rate mentioned in this thread...however (her's the weird kicker) of those doa's, most report that they recieved repeated doa exchanges before actually getting a good one. not sure what happens there, but it is not unheard of, nor unlikely to have a higher exchange doa then market doa. all i can speculate is that the exhange is coming from qcfail repairs, or something... also, did you try the discharge/recharge i've mentioned? it's gotten me more than once. hooked up the amp, and got the spark, and the thing is dead...messed with it, then threw it on the desk and tell the guy it's doa.... well, now i look bad, because he picks it up a week later, and hooks it up to see it working just as good as it did before....
