5AR4/GZ34 Rectifier Tubes

Is anyone currently making a tube of this type that rivals the performance of the best NOS Mullard tubes? I'm surprised that Sophia, Psvane and others appear not to have offered this tube. Suggestions?

I really like the 12AX7's of theirs. Retired all my old 12AX7. Very happy that this might be the tube era?

I will report out on the sound relative to the Sophia's when I get them. From what I understand, the earlier the tube, the more "chrome" there is in the bottle. If you look at 1960's tubes, just the cap has chrome.

I've got 5 months of steady use on mine with no indication it is starting to go. I guess we will need to keep this thread running to see if others find a short tube life. At $40, if I went through 3 a year it might still be worth it.
