What are the DC levels on the output lines to the speakers? If not zero, that can cause it.

Old NAD amps will have bad electrolytics. Block change them for maximum reliability.
I've also had tiny leaks in ceramic capacitors but that takes some finding.

secondary power supply caps go bad easy ,times two if exposed to heat replace capacitors , verify all voltage present according to the schematic , make sure you have the correct bias .

Kind regards sakis
