Wow-- a lot to mull over. Thanks to all for sharing your knowledge and experience. I have a pair of RCA 5751s that the seller told me are very early production, with shiny black plates, "RCA" in tall white letters & extra mica spacers, but they sound SO different from 12AX7s in the Perpetuum that I emailed Kevin at Jenison Audio and he said that using 5751s won't harm the unit but absolutely will change the RIAA EQ in this type of phonostage. Maybe after I gain some more experience I can revisit the 5751 vs. 12AX7 issue. The Psvane tubes caught my eye, along with the Tianjin Full Music 12AX7s; both are interesting... but pricey! Thanks again to everyone for much to consider.
What are some favorite NOS 12AX7s for phono?
I recently bought a new phonostage here on Audiogon. I wanted something made right here in the States like my last tube preamp,so I pulled the trigger on one made by Jenison Audio;the Perpetuum model. I checked and he(seller: dividebytube) doesn't have one listed for sale right now, but I have been really happy with it. I have a VPI table w/ SME 309 arm, and right now I'm running a Dynavector 10X5 high opt. MC phono cart. I have tried Sovtek LPS 12AX7 tubes and liked the treble detail and "crisp and clean" sound they offer, but I am definitely looking for more of a 3-D sound. I am open to suggestions for NOS (or modern production) 12AX7 tubes that balance detail and warmth, sort of an "updated vintage" sound. I welcome any suggestions.
