The first thing to do is replace the big Electrolytic Capacitors in it's power supply. If that does not cure it then you might have to replace the main power amp, especially if it is a single IC amp. In fact if it is one of them replace it before you fit new capacitors.

This may be a power supply failure, and or a short in the output stage, and in the drivers for the output stage.

This is not a repair you can do at home unless you have a lot of experience in troubshooting and analysing problems in power amplifier equipment.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Loud buzzing noise.


If you pull out the "input" cables and the noise stops, you have a problem with the "ground" and you have to check if there isn't a loose contact inside the plugs. If it doesn't stop, your amplifier is the problem and that mostly is a bad contact on the board in the pre-amplifier area.

A lound buzzing sound is an indication that the Driver (transistor) for the amplifier final is bad. This is not so much a buzzing and it is extreme in loundness.

Constant buzzing in my 15 W amplifier


Make sure you have a ground prong on your power cord. Most input jacks nowadays are closed circuit. They have a switch built in that won't allow any sound without the cord plugged in. You may have a damaged jack that will give you a loud hiss, a loud hum or crackling depending on what volume your controls are set at.
