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.

To quote Bicycle man, "It's a pity to think that good current production 12ax7's are so lame -- what to do when it is time to buy new tubes?", which is what I was responding to. Where in that post was "saving money" mentioned again? FYI: The EAT comes with the cooler/damper attached, and you'll ALWAYS see them advertised/pictured that way. To quote Ivor Tiefenbrun(founder of Linn Products), "If you gaven't heard it, you have no opinion."

Right! And good luck getting anyone to send you a demo tube so you can form an 'opinion'!

I'm more interested in how these TechTubes will sound. They should be ready (finally) to release them this month:

The have a new (for 9-pins) internal structure that uses CRT technology. And at $30 a pop (or so) I'd be willing to try a couple ;-)

Thanks Rodman! I have read good things about the Winged C el34's. The National el34's look nice, too. Great information!

I use the 12ax7's in the pre-amp phono stage.

Cheers!
I am trying to find some tubes to replace the six JJ 12AX7s in my Fisher 400. I am wondering if you guys have any suggestions? They way everyone is talking I might be wise to try some 5751s in there. Any input would be greatly appreciated.

Thanks,
