Seeking a Warm 12AX7 Tube for Preamp


Hi All-

 

I got hold of a newer tube preamp. I bought some match ed JJ 12AX7 tubed and after they burned in for a bit, they sound very strident and bright. Can anyone recommend  a tube brand that will be warmer in the upper mid and high frequencies? I can't afford NOS. I'd like to keep it under $100 for the pair matched. Viva Tubes has the new Mullard reissues, PSVane Art Series, Electro Harmonix Gold Pins, and Tung Sol Gold Pins in their new stock that are matched. Any suggestions?

 

Thanks

GE 5751 Triple Mica Black Plates did it for me. 
I know many folks despise EBay for tubes, but you probably can pick up a matched NOS pair for a few bucks under your budget to try out and see if you like. Make sure to check the seller’s feedback and that the seller accepts returns and you should be fine.  GE 5751 Triple Mica Black Plates are very desired excellent sounding tubes and in most tube reviewers top 10 lists.

@stereo_gen I had the Sovtek 12AX7 LPS in my Black Ice FX Glass Tube DAC as the tubes selected when I purchased the DAC from Black Ice. Those tubes sounded ok in the DAC and thought I’d try them in my Phono Pre and they sounded pretty bad. I put them back in the DAC feeling there might be something better out there and ended up trying some NOS RCA 5751 Triple Mica Black Plates off EBay for the heck of it and I was blown away… MAJOR DIFFERENCE !!! Much more musical, more analog sounding and for the price you can find these for they’re absolutely a steel of a deal.
