This is my first valve amp so I can not compare to other units but I definitely don’t regret buying thIs. Love the sound the bundled valves make although there is a buzzing noise. I understand that the buzzing noise can relate to the valves so looking forward to try something else in there too.

I have a tung-sol 6SN7 that stopped humming after about 72 hours of burn in. See the link below for details on how to do it with the DarkVoice.

I had the same experience. My Tung-sol 6SN7 is quiet now. I don't get how this works but I'm happy there's a solution. (Stock tubes had no hum in my case.)

I am curious whether its the amp or the tube that changes after 72Hrs, making the hum disappear
After 72 Hrs, if you insert a new 6SN7 tube, does the hum come back?

In my experience each tube needs it's own break in period. I don't have many tubes, but each hummed differently and each needed time to burn-in before the humming went away. Now there is no noticeable hum from any of them.
