User Feedback for Sophia Electric Blue Glass 6SN7 Tubes By James from Washington, D.C.

"I love the blue glass 6SN7 tubes. They are a definite improvement over the regular Sophia 6SN7 that I had peviously in my amps. The new 6SN7s work beautifully with the blue glass 300b and 274B tubes I have in the amps. Music has a natural flow and instruments and voices sound so real. I have tried many 6sn7s and I have to say your blue glass version is the best I have yet to hear in my 300b amps. Congratulations. " -- Jim
