I know from corresponding with keith that each tube is used a bit differently so you may get way with not changing all four. That said, I wouldn't do it unless you change all four since your going to create an unbalanced picture sonically.
5751 tubes in Herron phono
Has anyone tried a 5751 tube in the Herron VTPH-1 Phono.
I put in a Valvo E81CC '66 tube and it sounded so much better than the stock tube that it became a close call to which was better, my EAR 324, or the Herron.
Will the X7 replacement continue this trend?
