ARC Ref 6 tube replacement

Looking to replace stock tubes in my Ref 6. Anyone replaced their stock tubes? I also heard that that the NOS Tung Sol 6550 is an excellent tube for the power supply. Anyone have knowledge of this?

Do u mean there are no better replacement tubes than those you mentioned? If so can you explain the difference in sound with the NOS Tungsol 6550 blackplate compared to stock power tube?
