Here's the only new production 12AX7 worth thinking about, if you are able to appreciate the differences/improvements in sonics that the right NOS tubes provide(and it's obvious you do): (http://www.musicdirect.com/product/73403) With regards to EL34s: It's been quite a while since I've used that particular output tube, and had Svetlanas last(the original company was still in business). I've found the Winged 'C' 6550 to be an excellent replacement(sonics and reliability) for the NOS outputs that I used to be able to afford in my present amps. Matched octets of anything worth considering in NOS outputs are virtually impossible to find now. If Siemens made a 6550, I'd have to try them. Consider these, or the Winged 'C'(St Petersburg plant), for your EL34 needs: (http://www.upscaleaudio.com/Siemens-EL-34_p_62.html) (http://www.upscaleaudio.com/SED-Winged-C-EL-34_p_63.html)
Rolled some 12ax7's recently...
Hi All,
I went through my supply of 12ax7's recently and found some goodies.
I recently compared Bugle Boys to Telefunkens in the phono stage of my pre-amp. Interesting (to me, at least). I found the Telefunkens to be nice sounding; very clean and clear, very nice detail, over all a very nice sounding tube. The Bugle Boys, however, were magical! WOW! Timbre was so much more apparent. The soundstage depth and width increased; especially the depth. The music seemed to come alive and glow. It was much more captivating.
I found such a dramatic difference between two high quality tubes very interesting.
I have yet to try 10m's, and 70's Mullards that I found. I will report when I do...
By the way, NOS Sylvania's sound nice in the line-level stage. All tubes reported are vintage NOS. I match them with my tube tester. And, I do not change the volume setting between tube brands tested.
Any comments are more than welcomed! I appreciate any information on your experiences with 12ax7's. The price of some of these NOS is incredible; I am glad to have these nice examples in my collection!
Cheers.
