5AR4/GZ34 Rectifier Tubes

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...

I'm new to this so I'm still experimenting, but would like some expert advise. So I can start in the correct direction and not waste time and money.

Wig, I have not heard of the Ked Red VT231. Where is the best place to get a pair to try out and even buy? What do I look for? On e-bay? BIG Thanks!

Bigkidz, same question, as for the NOS Tung-Sol 6SN7 Where is the best place to get a pair to try out and even buy? What do I look for? On e-bay? BIG Thanks!

It's actually Ken Rad, not Ked Rad. I have a few pairs of
these and they are indeed nice, however, in my system, the
Shuguang Black Treasure CV-181 "Z" (original
series), was better sounding.

I also like the Sophias a lot, very nice.

Like Wig stated, it really comes down to preferences...

Another positive vote for the new Genalex GZ34/U77 5AR4 rectifier tube. I've bought 4 of these for my amps and the Genalex GZ34 is a splendid sounding tube, especially at the price. The tube is dynamic, quiet, refined. I think this is a great tube for the money.

Happy Listening!

I still have not gotten a solid response. I'm just looking for some help so I don't buy the wrong ones from the wrong place. Much appreciated!!
