Ref 5 / 5se and different 6550 tubes

[turntable]

Has anyone rolled the sovtek 6550 tube in the ref5?

Many possibilities like winged C, Tung Sol to name two.

Hi I have Ref5 and I have done exchage in two steps: 1st to Fender and it was better, second to6550 Tung Sol - 60s Black one and it is now again better than previous. Additionaly I have exchage the 6h30 to DR version and it is abother step of improvement.

audition from where? Just thinking out aloud. I think tube rolling the 6550 could have some major benefits, so thought I would ask.

I may be buying a Ref5 and I was planning on replacing the tubes with NOS tubes if I buy it. I've been wondering if it's worth replacing the tubes in the power stage. Have any of you tested replacing just the power stage tubes to see if it makes a difference?

I did change for TungSol 6550 Black Plate from the 50' in my Ref 3 - BIG improvement.
