i dont know if they will take care of this or not
as i have already opened the seal and "filed" the case for muses01
it is my fault, that i didn't even test the unit first before i opened it up and start the case filing.
and rigjtbefore i first tested it, i changed the op amp to the 1611
i wonder if they will say, OO you damaged the unit already, you are on your own now.
