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?

Has anyone tried the Weber WZ68 solid state rectifier .
It plugs right in the place of the 5AR4. I ordered one to try on my New VTA-ST-120 (Bob Latino) Amp.
I do not have it (The Amp)yet ,but he recommended it as an upgrade to the Ruby 5AR4
Does anyone have any thoughts or experiences with the newer Tung Sol GZ34 rectifier tubes? I was looking at the newer Sovtek GZ34 tubes because I'm on a budget but I got a recommendation to look at the Tung Sols.

Thanks
