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*.
http://www.r-type.org/exhib/aaa0426.htm
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

*Big Boys*
So  ordered a  bunch off ebay, and will arrive next week
Will post a  review.
can not find much on the INET about the 12BZ7,, anyone have experience with this tube?

,,,wait a  minute,,Not $50 each, I am bidding ona  Philips Miniwatt E80,,,ends in 4 hours Current bid
~~$114/10ship~~~
UNREAL.
Thats crazy,,, as i say,,
IMHO
all E80's , are near equal, the sonics are so ~~Miniscule~~ (as my tech guy in  Bato Rouge would say) , its not worthm paying more than $50 each. 
at least in today's, jan 2020 selling price.
Just think if word gets out about this tube as a  ~~Super Tube~~ swap for the AU.
Prices could double over night.
Once I see prices jumping, I am going to load up and scalp later.
I've lost so much money on buying and selling tubes past 2 years, time for me to make it back/ anyway, back to 
12BZ7.
If that tube pops the AX section in my Defy,,thats another tube that could jump in prices.
They go cheap now.

Well 12au7 suck, so it’s not uncommon for folks to find a different sub type that blows all the best 12au7 away. Many tubes operate similarly to a 12au7 and do it better. 12ax7 is a better sounding tube albeit with a very different use/purpose, and you may have a much harder time finding a sub to beat the greats.
