Good Tube Selection for Atma Sphere S30?


Looking for recommendations on 6SN7 and power tubes that will compliment the OTL wonder of this amplifier.

I think Ralph would say don't mess aroung with the 6AS7s - though I did buy the Russian versions from The Tube Store.
Russian power tubes are fine! The only Russian 6SN7s worth looking into are vintage made in or before the 1960s.
I was on Sophia Electric's website and saw they carry 6SN7's for $100 apiece. That seems pretty steep and I don't know of anyone that has used them. Just mentioning another source for you.
