On my first day with my MKIII, I was getting noise out of my 6HM5 Yugoslavia tubes. When.i was talking to the seller, he mentioned that they were new to him and he hadn't tried them.
So I decided to run them last night while watching TV. Maybe they just needed breaking in. After a few hours of being on, with all four tubes in and no mysic playing I started to hear noises. It was like a hiss and a crackling. It seemed to be coming from the power bar and not the amp. As soon as I turned the amp off, it was gone. Bad tubes? Lustening today with the Voshkods in and it sounds great.
Are these defective tubes? Could they be the wrong tubes?
