His handle is daveds50. He was doing warranty repairs for eD when they were in business, so it might be who you are referring to. Well I'm on my 2nd eD driver. The first driver was making the amp make a clicking sound. I sent the amp in and it checked out fine. I had him rebuild it with better quality components since he had it. This made us think it may be the driver causing it. Not long after, the amp totally went. I sent it back for repair. I had another eD driver on hand, so I put that one in. The sound difference was night and day, so I know the first was definitely damaged. I've been using the seond for a couple of months, but now I'm hearing the clicking again. So, I'm going to try replacing the driver in hopes that it saves the amp from damage again. If I hear no clicks for a while, I'll figure it was the driver. The eD thread is starting to get more and more people saying their drivers are taking out their amps.
