12BZ7 ///12AX7


Could not finda  topic for tubes, so am using amps section.
After making the amazing discovery of the E80CC as sub for AU~~E80CC blows away every/all AU's, including the *Holy Grails/Siemens,Tele's*.

at least in my Defy7, the swap was more than just significant, the Defy came to life from the grave.
I found the Siemens to bea  miniscle superior to Philips = both are equal IMHO, and the valvo Red label E80's going for $$$$$$$$$$ is a scam. Don't buy into it. 
Right now that tube  is going for $50/each. When word gets out  ~~Super Tube~~~the price will rocket, as that tube is not being produced any longer. 
I've loaded up on the Philips label.

so i figured,, maybe there is a  
~~Super Tube~~ for the AX..
After days/weeks of research,,i found this
12BZ7

I have tried Mazda 12AX7( S) silver plate with Sylvania 12BH7(A) in my Rogue Apollo’s upgraded to Darks at factory, actually on Mulveling’s recommendation. I am very pleased with the results. Currently, I am using  Mazda 5751 silver plate 3mica and like them. They sound more revealing, albeit not as quiet as the silver plate 12AX7S. I understand it’s a matter of personal taste, but am I missing something here?
