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?

Just put my new golden lion genalex in my Modwright power supply. Right out of the box there was an improvement in the base depth. I am using the Sophia's for the Sony ES5400 player and have been toying with the idea of some 40's NOS Sylvania's. Has anyone moved on from the Sophia's?
Goose, I think these Gold Lions are going to be hard to beat based on my experience so far. PSVane claims they have a 6SN7 equivalent that people really like in ModWright gear. One of the ModWright website photos shows an Oppo with the PSVanes. You might give Dan Wright a shout and see what he has to say about them.
Brownsfan I am actually surprised how good the gold lions are. Perhaps there is hope for new stock product. I will need to check out the PSVanes. Thanks for the tip.
Goose,

I had the Sophia's in my system for about a month before I started experimenting with NOS tubes; Sylvania Chrome Dome walked all over the Sophia's but they sold rather quickly.

Also tried the Psvane, too dark for my taste...
Wig, thanks for the suggestion....I will need to check my Sylvania sources. What vintage were the chrome domes...1940's or? Hope you are still enjoy your Crescendo's.
