Questions and answers
SR7300 one left side channel is distorted, after some time slowly it become correct ..
The distortion in the left side channel of a Marantz SR7300 that corrects itself over time could be caused by a failing capacitor or resistor in the amplifier circuit. Over time, components like electrolytic capacitors can degrade, leading to inconsistent performance that improves as the component warms up. Checking and replacing capacitors or resistors in the power amplifier circuit may resolve the issue.
