I second the Ei 12AX7 suggestion. The older Ei's, with the white lettering are the ticket. FWIW, I am currently using a pair with a CAL Alpha, and I prefer them to NOS GE 5751 that cost a lot more $$. I may be mistaken, but I think Ei is still in business. I have a pair of (I believe) current production Ei 12X7 Gold Pin Elites, but they don't sound as good as the older ones.
12ax7's to roll
Happy Holidays A'goners. I have a Rogue Cronus Magnum that I bought from Agon. I love it and I'm curious about tube rolling. A very reputable tube source that most tube fans in the U.S. would be familiar with, recommended replacing my 12ax7's with Telefunken 12ax7's. They're really expensive as far as I'm concerned. I'm not wealthy and have kids in college. I could certainly swing it but is there other alternatives that cost less than $230 for a matched pair that will give me a good tube rolling experience? I currently have Sylvanias and I love the sound. I'm just curious as I've never tube rolled in my life.
