Lab12 is a good company and their products sound great. The Music Room is a safe bet when you have a problem. I just purchased a Cyrus integrated amp from them. I had an issue that led me to believe the unit was defective. It wasn't, it was a simple problem but they were great to deal with. Hopefully you get it straightened out.
How much hum is normal from a new tube amp
I just bought a great sounding Lab12 Suara KT120 tube amp. The issue I am having is a hum that is coming from the transformers. I can hear it with no music playing faintly from my listening position 12 ft. away. The question is, should I return it, or is this normal acceptable.
