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'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.
