845 tubes. New not old stock

My Triode Corp of Japan 845 amp will need new power tubes within the next year or so and I am curious which 845 tubes are being by used by others and how much they are liked. I currently have Psvane 845T, which sound good. These are the original version. I tried out a pair of Dragons which were not as lively as the Psvane 845T's. I am considering Psvane 845 Tii or the KR 845's. Are there any other new manufacturers making 845 tubes within the last 5 years? Unfortunately all of the NOS 845 tubes are out of my price range ($7500!). I would like to keep it under $800/matched pair. 
Thanks all
Has anyone had 2017 experience with Elrog?  I would like to try them, but the data I've found online is mostly from their early days and it was hard to tell if the troubled ones simply failed, or failed and caused amp issues (I never read definitively that the latter happened to anyone, and I also realize it's based on amp design too and the amp's fault handling capabilities).

If so, where did you buy them?
I have a collection of six dead Elrogs. Purchased them through the years. Wish Elrog would get their " stuff " together because they were great  tubes. I am currently running the Psvane 845WE's and I am pleased with them.
I would have to say that the Sophia 845 MK3 are also nice tubes. In my system, the Psvane's have a more controlled,  refined sound to them and in the same system, the Sophia's have a slight tubby sound to them. Both are good tubes. When the time comes for me to replace, I'll go with another pair of the Psvane 845WE's.
i have 4, 845 elrogs built this year and they are absolutely fabulous - can't say enuff good things about them.  i too have the same amps as the OP.

i purchased all direct from Thomas Mayer and find the service wonderful 

sorry if i sound like a fan boy - but i really love them  

I love my Triode also. Really a great integrated. My Psvane 845t, first generation, are nice, but getting old. We listen 10-20 hours a week. Not sure if this posting has helped me make a decision, but, I do have some more info. I appreciate everyone’s input. 
I have had the Psvane 845T MKII and WE845. I would recommend the Psvane WE845 tubes. They sound wonderful in my system.


Happy listening!
