You have a couple of things that might be going on. One the emitter resistor one the channel that is bad needs to be replaced or the bad channel itself need to be repalced. This does take soldering to fix it. You might need to take to a repair shop.

Crackling when turned on then high pitched howl and sound like vinyl being played loud and having stylus dragged across it is the only way to describe the noise after howl. was being used and did crackle...


You didn't say whether it was one or both channels. The word to describe the noise when using a turntable, back in the days, is called Acoustic Vibration. Your issue is not that. I can be an amplifier oscillating, for the high pitched sound and the crackling could be DC Offset*meaning a damaged amplifier) If you need further assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. Thank you.

My Technics SUV 660 is making a crackling and popping sound regardless of where the volume is. It does reduce once the amp has been on for an hr or so. Also the speakers are not consistantly on. Any a


If the sound is on both channels then it's probably a device that is connected to both channels. I don't think it's the power supply. I rather suspect it's in the power amp section, since it's not affected by turning up the volume. If the amp uses one of those STK devices as a power amp, it could even be that.

Crackling from bass combo when I hit low notes


I'm afraid it sounds as though the speaker has been overloaded. The replacement for this will, unfortunately, be a new driver (the speaker unit itself).

Screaming crackling noise when very hot


Crakling sound is a symptom of loose or cold solder in amplifier section where the STK IC or Darlington transistor is located .You better re solder all parts joints there in order the crackling sound is gone.

Pioneer SA-9500 Extremely Loud Crackling


The volume control and tone controls are dirty as well as the selection switch. This is common for older units. These controls and switches need to be cleaned with an electronic switch cleaner which should be available from an electronics store. Spray each control/switch and work them (turn repeatedly). Repeat this procedure a number of times and the accumulated dust/dirt will be cleaned and the unit should no longer have the problem.

Please note that it is possible that there is a transistor or 2 that are breaking down that can cause this as well. If the cleaning does not resolve the problem, let us know.

Crackling power switch on NAD 3220PE


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:)
