If you have other tubes in this equipment that werent bright then the tubes might be the solution. Many times the system is too blame and it is better to isolate the offending component(s) and sell them replacing them with something more to your taste. I think it a mistake to use tubes or cables as tone controls in a system. You could end up with a bunch of stuff that is useless when you upgrade.
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
