I've had two tube power amps with KT150 tubes in my system the last few days and neither had any hum whatsover.
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.

@ltmandella My hum is coming from inside the unit |
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. |
While I’ve found the KT-150 Tubes to be the least reliable power tube I’ve ever used, they never produced hum in my amp (primaluna evo 300). Agree with the choir to return the amp for a refund or replacement. I had a similar issue with a Carver Crimson 250 amp and was lucky to work with a dealer who fully refunded the unit. Best of luck with your replacement. |
