Morning collective,
My NN50 hums loudly on phono input and I only have a dac connected. Unplugging the dac from the amp input so it has nothing connected still hums…
The dac is double insulated with no earth pin so I thought trying the link wire mod from the aux din outer ti the naits earth post , but still hums.
Before i talk to 7oaks do i need to try the other mod of linking the dacs case to earth? The only thing that silences it is phono shorties on the phono input.
Any tips appreciated, or I’ll talk to 7 oaks in case it’s faulty
Cheers
