ARC LS25 mkII noise level


What are the expectations on the ARC LS25 mkII noise level? Are these units supposed to be dead quiet in the system?

Mine adds considerable noise to the system. I swapped it out with another preamp (solid state) and the difference is quite significant.

Maybe a pointless question, but do you have tube dampers on the LS25? I have a LS26 and hear no noise. Maybe the tubes need replaced, take small steps to solve the issue.
Possibly vibration dampers under the componet. Mine is on AQ Feet. Contact ARC they are very helpful on the phone, the challenge is reaching someone on the phone as they are very busy. If you are buying new tubes look for the 6H30-DR, I have found them to sound better than the ARC OEM tube.
