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?

Mlsstl, you got me. I'm not an ee. I would have expected this from an output tube, not an ee. I had my ModWright for some time before I started rolling rectifier tubes, because I was skeptical. I tried a couple different new production tubes, got ripped off on a vintage Mullard, then finally got a good Blackburn Mullard. A short time thereafter, my back ordered Create tube arrived. All I can say is a number of people have found this tube to their liking, but not everyone.
While I have a Mullard 5AR4/GZ34, I find the JJ sound very nice, better than Shuguang, and a good enough option for me. Unfortunately, the Shuguang have proved more rugged/reliable.
I'm also rolling a JJ with all my expensive rectifier tubes in the closet. For $20 shipped, it's surprisely good.

I'm going to try the Cryoset JJ next and see if any improvements with cryogenic.
How would the sound of the Synergy compare with the Mullard Blackburn I am currently using in my Modwright LS100?
