Question about Amplifiers & Preamps
Im not sure if it is worth my time or money to get this fixed. I would prefer to do it myself if I knew what the problem was...
Anyway this AMP randomly crackles to the point of blowing your ear drums out. Not music just crackles, this will happen even without anything being played through the AMP.
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.
