Whenever I turn on my NAD 3220PE, there is a crackling sound for about 30 seconds or so and then it subsides and the amp works fine. I took the amp apart to see if I could figure it out and I've located the problem in the power switch. The part is sdu3p tv-3. I turned it on in the dark and saw electric sparks (or maybe they were not sparks, but arcs or something else) on the switch itself. I was wondering if anyone knew how to get a replacement switch or a way of bypassing this problem. (I am not above jerry-rigging, I just want this amp to work) Thanks!
