    I have a problem with my old amp (it has been passed on to my parents). It buzzes al the time, even with no input? The amp is a Sherwood R125. Can anyone help find the cause, I have opened it up but nothing looks burnt out. I am not the greatest electronics expert but would like to fix the problem myself as the amp isn't worth much. If not I will have to buy them a cheap new one.

    Does the buzzing change when you increase or decrease the volume? Do you have a tone defeat button try switching it on.

    Often the potentiometer in the volume control gets dirty and may cause problems. You could try some switch cleaner. Make sure befre you use it that it wont melt any plastic parts.

    Are you using a record deck?
    Does buzzing sound change as you move your hand near it?
    If you are it may be because your tonearm (pickup) is not earthed.
