Technics amp crackle and ''hiss'' noise

I got a 80's technics integrated stereo amp that makes a horrible crackling sound when switched on (even if it's muted) this goes on for at least 20-30 mins not continuously but whith about 30-60 sec of headroom. also when its playing it sometimes makes a small crackle noise. and last i can hear a ''hiss'' sound coming from both treble speakers (2 ch speakers) and i can hear it all the time when the amps turned on doesnt mather if i got a music source etc connected during playback or if its in ''standby'' mode or which channel that are selected. and this ''hiss'' gets louder when i turn up the main vol, and at max its VERY unbearable.

i hope someonne can help!
and is it worth fixing it, or should i go for a another amp?
sorry for my bad eng/ grammar.

I had the same problem. After I changed my alternator, the problem was solved.

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.

My su-g95 technics Stereo integrated amplifier wont play any noise. and when i adjust the volume it makes a popping/crackling noise. i am 100% sure all the speakers were hooked up correctly.


Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

Got a crackling sound then it stopped playing.now every time i load a cd i get no disc.


technics wont play cd-r or any copy cd's thats why you get no disc but if this is the case with all cd's then it sounds like you need a new laser unit, the crackling sound is your laser breaking up, there easy to come by on ebay plenty for sale worldwide.

Technics SU-G95 Amplifier, Intermittent popping/crackling noise


The heat sink has the power modules attached but also has 2 power transistors that become disconnected from the circuit board when the heat sink moves or flexes. The pins on each need to be resoldered (it helps to bend them a bit too, prior to soldering). Had the same problem on the same amp today and that was the fix. There was no sound other than a clicking when the volume control was rotated.

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.

Hope it may help you;

Noisy channel of receiver


Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?
