:The electrolyic capacitors are drying up. These are those small "cans" that are on the circuit board. A value the same or slightly higher can be jumped across the suspected one (pay attention to polarity) and them fire up the amp. Do this until you find the one that eliminates the buzzing. This is a quick and cheap way of finding out. Normally one would use a signal generator and a signal tracer to find this out. This is actually a very common problem when amps get older.
Hi Steve
: Can you be more precise about the fault. Is constant or.....? Is it affected by the Volume Control ?
: : I have an AU-101 that has a problem with noise in the speakers. The sound through the speakers sound like a wire is is arcing I've had it in many years ago to be repaired but the problem returned. I seem to recall the tech saying he replaced something that was breaking down. Is this a common fault..and if it is...does any one know how to fix this ??
