I have a NAD 218 amplifier the right channel output makes the sound as if the speaker is blown. (Left side sounds amazing) Any suggestion on How can that be fixed.
If you follow the schematic and compare left channel to right, the fault should become apparent.
I would suspect an output issue.
Here is the schematic. NAD 218 Service Manual download, schematics, eeprom, repair info for electronics experts

As a first check, remove the speaker leads and audio input leads, turn volume right down and measure for any DC> 50mV between the + and - speaker connectors of each channel in turn. You might expect to measure a lot more DC on the faulty channel.
