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?

The "Bugle Boy" was a series of tubes that were made by Amperex. There was no company named Bugle Boy. http://vintagetubeservices.com/page9.html
