6sn7 tubes for Atma Sphere amp


I will have the S30 in my systrem this week and would like to know what 6sn7 tubes are being used by AP owners.

Change out all 6?

I have had in my AN 300B amp the TS RP and Sylvania W Metal. The TS was the better of the two.

Congrats from me too...belated. The Atma amps are great and rise to the occasion. Some tweaking helps.
.Contrary to preconceptions that the input tubes are all that matter I changed all the output tubes to rca nos. 28 tubes in my ma1. Very good investment. While changing driver tubes has been so-so. But then i started from nos sylvania to begin with.
