Check out Cryoset's website. Ron Sheldon's Cryoset offers several fine brands of 12AX7s. I consistently enjoy the cryo treated Gold Lion tubes. Very quiet neutral sounding tubes with nice dynamic swing that stay quiet for a long time. I'm sure Ron would be happy to discuss his tubes with you and recommend tubes that would most likely deliver the sound you are striving for.
what tubes for eastern electric minimax phono?
My EE phono, purchased here on Agon, came with Tung sol AX 7 tubes in all three sockets.The sound is commendably neutral but there is quite a bit of tube rush/noise. Any suggestions for a reasonably priced tube that is quiet but neither bright nor very warm. I dont mind a bit of warmth so long as the treble is still there, not chopped off.
