Buzzzz sound in amplifier right side speaker

 

[dudio]

Swap the left speaker with the right speaker to rule out that the right speaker is bad.
If both speakers are good on the left channel, then something is going on with the amp.
Does the buzzing sound happen with all inputs? Try using the FM tuner if it has one. Try another input. Swap the left and right input wires and see if the problem switches to the left side, meaning the input wire connection is bad. If all sources with known good working wires gives buzz always on right side, then the amp is bad.
