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

@cey You can buy the Mullard reissue almost anywhere that sells tubes for ~ $25 each/$50 pr.   Amazon, Ebay, Tube Depot, Viva, etc.,

Stay away from PSVANE. Look for the new Mullards or the Genalex, Gold Lion. They’re about $106 a pair on Amazon, don’t know how much on Brent Jesse.

If you’re not opposed to NOS, or used that measure well, try the Raytheon 7025.  A low(er) noise 12AX7 that I have found to generally produce a full sound that is on the warm side.  And they can be found for very reasonable prices.
