No sound means probably bad circuit. Crappy sound on MC doesn't reflect cheap cartridge, but reflects the fact that the cartridge's output is too high for the MC. I'd try spraying some contact cleaner in the switch and hoping that helps. If you have a good local technician (not a high end repair guy) he could probably figure it out. Keep in mind that for $100 you can get an external solid state phono preamp that would run through one of your high level inputs. Good luck
NAD 116 - MM phono stage not working
Hoping there are other NAD preamp owners out there who can help me. I hooked up my turntable but get no sound if switched to MM on the back. When I switch to MC I get sound but it is awful...probably due to my using an inexpensive magnetic cartridge. What could be the problem? Is my phono stage pooched? Does this sound like a costly repair? Thanks for your help. Matt
