I would try switching the tubes left to right and see if the problem follows the tubes.
Tube Questions - Audio Research Reference 5
Hello All,
I have an Audio Research Ref 5, recently, there has been some related noise ( am assuming ) at around 950 hours of use. It only affected the right channel. Ive ordered replacement tubes, but on the meantime replaced the 4 linestage 6H30 Solvtek Tubes with the ElectroHarmonix Gold Plated Version. The 2 tubes in the power stage remained the same. There was some improvement, but it seems the bass is still rolling off on the right channel. I had a few questions:
1. What does a bad tube in the powerstage VS linestage sound like?
2. Is it possible that a bad tube on a REF 5 in the powerstage can affect only 1 channel?
Thanks in advance for your help.
