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

I've got an assortment of 12ax7's and my suggestion for warmth would be NOS Mullard (IEC variety are less), Brimar (can be bought from Langrex in the UK for  a reasonable price), or if new issue the Gold Lion B749.  The reissue Mullards didn't do it for me.  I have used NOS Amperex as well and they tend to be a little more bright and detailed. I'll also second the NOS Matsushita made with the Mullard tooling. These are very good and  should fit in your budget.  I would try to stretch the budget a little bit because under $ 150.00 opens up a lot of options.
