In Reply to: RE: Fed up with old stock 12AX7 RCAs dying or becoming microphonic! posted by Paul Kehayas on December 21, 2016 at 18:16:54
The B759 is quieter with its spiral wound heater; and it has better tone all the way up and down the spectrum.
The latest production B759s also have lower microphonics and noise than the earlier production from a few years ago.

Jim, I may have heard the earlier first run Genelex 12AX7. My ears are falling off sensitive wise on high end frequencies. I heard to 12000Hz. My amp is unique and tubes sounds different in different amps.
Based upon your experience the Genelex may be as good as any vintage tubes. But my unique circumstances the RCA worked better for me.
You would definitely prefer a tube with more top end energy than the Genalex, no doubt! Depending on the circuit you may find it works well in conjunction with other "brighter" toned tubes.
I'm 65 years old (yikes!) and I'm definitely aware of my own hearing limitations also. The advantage I DO have is I get lots of feedback from customers and that allows me to have a pretty good idea of how tubes sound to people besides me.
