I have a mk vi+ and im experiencing which i think is an issue. Im having slight buzz in the left and right channel right after the right side warms up and "clicks on"
im guessing when the transformer turns on. this is happening when i use my sony7506 headphones(63ohms) SE in the back and when i use balanced preamp outs. when nothing is plugged in to the Little Dot except headphones or my power amp the buzzing is there, when i play hard music its not bothersome but it drives me nuts when im listening to classical. the symptoms are there no matter where the volume pot is at. Im using dacmagic ballanced as source and its not the dacmagic, my little dot mk ii is dead silent. I cant hear it when im using my hd600(300ohms) connected through 4pin xlr and that is fine, but i like to use it as a preamp and the buzzing is still there. I tried different tubes, i have changed the gain settings, and i have sent it back to china and extensively explained this and it shipped back just like it left. has anyone tried the preamp outs? Or has anyone tried the SE OUT with similar impedance headphones? Any help would be really appreciated.
I tubes that i have left in my unit are Power: RCA JAN 6as7g Driver: Tung-Sol JAN CTL-6su7gty and this combination is my favorite.
