Question about Amplifiers & Preamps
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!
Hi, i would try flooding trhe switch with CRC 2-26 for a start. Itr may recover some contact integrity. A jerry rig solution would be to bridge the switch contacts and leave it on all the time(i leave my amps running all the time) or if as in Australia you have a switch on the wall socket use that,
OR purchase a new switch from here. Not sure how you would go through NAD, probably dont have any in stock as a spare these days.
or if that does not work out, I could get one to you through ebay. Used to be quite a common TV switch, but I also remember replacing then in Nad amps, many moons ago ;) I think I still have a one in stock myself, packed away from when I was a NAD service agent:)

I have this amp & believe it still sounds very good. Keep it or sell it on craigslist. It will sell very quickly.
