I thought I had read about this tube form Steve so did a forum search. Check out his comments.
From this Link:
https://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1510110956/0#0"The TORII JR is designed to use your favorite 6922 input tube, one per side. The 6922 is fast, clear and dynamic.
We have shipped the amp all summer with a new Chinese 6922 tube called a 6N11. It is the fastest we have heard.
If we could get consistent results in a TORII JR from the 6N1P that would have been the tube of choice to ship the amplifier with because it is so warm by comparison.
A NEW TUBE OPTION for the TORII JR is the Russian 6N5P. It has the warmth of a 6N1P with the clarity of the 6922. The tube has a touch less gain which helps keep the amp from getting aggressive sounding.
I will be shipping the TORII JR with these fine sounding input tubes while quantities last because as the designer of the amplifier, it sounds the way it's supposed to with this input tube, which is musical, honest and seductive.
This tube should also work in place of the 6N1P in any of our amplifiers and pre-amplifiers too.

And this one:

Reply #28 - 08/24/16 at 10:44pm That is my maker's mark. I have put it on several random products that have passed through my hands to see if it feels right, which it does. The SE84UFO3 will be the first item to carry the mark from serial #001 on. It's only fitting really, the amp that started Decware and here it is today in it's 20 year fruition having peaked out in this consistently simple form.
Interesting story, I always figured if money was no object and you wanted to see how far you can take the fidelity of a Zen Triode using the 6P15P-EB tube it ships with, it would likely involve inter-stage coupling transformers to replace the cap between the input and output stage.
This is where I learned (as usual) there are no consistent roads of assumption with this design, and for what the transformers improve they also actually take away. I suppose the strength of the Zen is the very fact that it takes the weakest link in the circuit's signal path - the capacitor - and makes it the amplifiers strength. It does this by using the effect that the cap has on overall phase angle in the fundamental voicing and output stage design to a point where like a fine piano, it is tuned... don't mess with it.
I have been listening to Dan's and my own pair break-in for the past few weeks and they are like magnifying glasses. I have been playing with a variety of input tubes to get a feel for what the amp will bring to the customer. The input tubes include 7 expensive NOS 6922's, 2 outrageous 7DJ8 long bottles, 6 NOS 6DJ8's, several hand picked 6N23P,
a few hand picked 6N5P's, and of course the stock 6N1P-EB that all Zens have shipped with not to mention the latest 6922 from Shuguang, the 6n11.
If we take all of these, the 6N1P is the juiciest. On the other end of the scale is the most pristine detail nearly to a fault tube, the new Shuguang 6n11. It's resolution is exhilarating... with good recordings. Nevertheless, the insane speed and resolution of that tube with several NOS tubes being possibly as good with overall perhaps better balance, the combination with the UFO output transformers is really a new benchmark. Tonight it bested a system that should have laid it to rest.
Boy, this hobby just never gets old does it Wink
