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?

If I change to 5751 will I need to change out all four X7's?

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.

Yes I have. My favourite combination is:

Brimar 12AT7 black plate
Tesla ECC803s x2
GE 5star 5751 triple mica x2

This produced the best mix of detail and warmth/body.
