Problem was in volume pot and appears to be solved. For test purposes I connected it to a pair of old Spica TC-50's I have laying around and this combo sounded wounderful for acoustic music. I was not aware that the 7020 could drive a decent 4 ohm load. To me this little amp is still the best NAD product ever made. Thank you for your responses. Audio 44

I am suddenly getting distortion inthe left channel on this unit(used in bedroom system) and would like to know where I could get the unit repaired in the greater NYC area(reasonably of course). Also, should I try something simple like replacing a fuse? Any help appreciated thanks, Audio 44
