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?

Goose,

I believe they are from the early 50's and my Crescendo's are unbelievable, I'm still amazed each night I fire up the system and being transported to a LIVE performance...
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...
Goose,

Have you upgraded your MW PS to the 9.9? It's s worthwhile upgrade.
Joeyboynj,

I haven't any cryo treated tubes but have read it's a mixed bag, some like and some don't.

In regards to 6SN7s, I've tried both Pvane, Sophia and prefer my Ked Rad VT231 by a large margin. Pvane was dark sounding, the Sophia were good with soundstage restriction compared to a true NOS.

Actually, I found the basic Sylvania Chrome Dome to be superior the Pvane or Sophia, but I guess it comes down to preference and system matching...
Good to see that the Create 5AR4's are being discovered. I really like mine but their 6SN7 are not on the same level.
Brownsfan,

Good to hear your initial impression, where did you purchase them?

Thanks
Guys,

Thanks for the info. Brownsfan, I know it take about 50 hrs for new tubes to settle but have you heard any new changes? Looks like I'm going to be ordering this one too!

Thanks
My tube arrived today and I have it running in for 3 hours before an initial listen...
Guys,

After running my Gold Lion Genalex for 4 hours, my initial observations are on par with Brownsfan. The GL beat the Create in transparency, lower floor noise and combines dynamics with that rich body we're accustomed to with Mullards. Also, the GL are more precise in image placement and overall sound-staging.

The GL are in for the long haul...
Definitely a Great find at $40! I still haven't found a 6SN7 that beats my Ken Rad VT 231 but I'd be willing to try some Gold Lion Genalux if they decide to make them...
Should sound better after about 70 hours and I have not had the opportunity to try tungsol.
I tried the Create 6SN7 in my cd player and they weren't close to my W's or Ken Rad VT-231; I'd be interested in the Tungsol if they were available at decent price...
Joeyboynj,

Like Rodman99999 said, the Tung-Sol are very expensive but you can find them along with Ked-Rads VT 231 and the Sylvania VT 231 are my favorite and be found at Bent Jessee Recording...

Geoffkait,

Very good! The Ken Rads are very good but if you want more air, dynamics and bass the Sylvania VT 231 are even better...

I acquired a pair of Sylvanias Bugle Boys a few days ago and they're even better than my Sylvanias VT 231; better precision, transparency and captures more low level detail, ambiance and a deeper sound-stage. My VT 231 are woodier/bloomier/thicker in comparison and is easily heard on cellos, violins and guitars, types of music I typically listen to...
Geoffkait,

They were manufactured by Bugle Boy around 1952 and have three holes in each plate verses two in typical tubes and sounds phenomenal, a great tube and a good find...
Geoffkait,

Sound wise, they are both very similar but the Bad Boys doesn't have the bloom and extract more details from guitar pics/slaps; they're just more transparent in pulling out the slightest amount of ambiance and details from the recording...

The VT 231 may be a little smoother due to the bloom they project but It's a matter of preference for sure.
