Quoted from manadams:
Mine was rock solid when I got it. After about 30 plays it was missing short and found out it was related to my AC running all the time lowering my house voltage a bit. I bumped it up from a 26 to a 27 on coil strength and it would miss left. Pretty sad I have to make sure my AC is not running for it to play right but there is no setting between 26 and 27 to find a happy medium.
Do you have the upgraded powersupply? Sorry...didn't go back to check prior posts.
