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?

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?
You should try a GE 5AR4 - I used one in a Melody SHW 1688II preamp - best rectifier tube I have ever heard. Still in my tube stock.
