Tung Sol 6sn7gtb. Been giving it some time today, very detailed, fast,slightly cool, very good soundstage and good bass slam, so far an excellent tube.

Scutey:

I went back to the NOS USA Tall Bottle Tung-Sol 6SN7GTB. Smooth. Deep Bass as well. So I have narrowed it down to 2 Driver Tubes: The Tung-Sol and the Sylvania.

hopefully i have a Syl 6sn7gt coming either today or tomorrow, and I've just won an auction for a pair of Shuguang treasure cv181-z, they should be interesting!.

 

[Scutey]

... but so far the Tung Sol is the best 6sn7
I've heard.

I agree. I kept going back to the Tung-Sol. What about the PS Vane? That is tempting as well.

Just wait till you find a Western Electric 421A Power Tube. Or if you can find a NOS Tung-Sol 5998. Earlier Posts mention they are the same Tube.

If the shuguang are nice I might give the PS Vane a go, That Western Electric seems to be a fairly rare tube as I've not seen any for sale recently, although I will keep on looking!, I did have the chance to acquire a Tung-Sol 5998 a couple days ago but I hesitated and when I went back to look again it had gone!.

Anyone use a 12SA7 in a Darkvoice 336se?

 

[Scutey]

Because the "coke bottle" tubes look so good lit up at night though I'd take a few pics, this is today's set up, driver,Tung 6sn7gtb tall bottle and for power RCA 6as7g, the RCA is sadly a bit too microphonic, but still looks pretty good lit up.

I have the exact same RCA tubes set up on my DarkVoice Dead silent as if you were in the vacuum of space even through my HD 800s

Four tubes arrived yesterday, RCA 6SN7GT Sylvania 6SN7GT, also RCA 6AS7G and a Sylvania 6080wb, only the 6080 was silent. In total so far i've dought 7 for my DV and only 2 in total are silent.

You can see my DV workhorse sitting on top of my AC line conditioners. Monster Power HTPS 7000 and Monster Power AVS 2000 because I was suffering from some AC noise coming in to my power into the building . I had a little noise coming from the drivers of some of the florescence lights and LED's I change those to a different brand with better filtering in him and in some rooms I put back old incontestant lightbulbs, and that took care of the rest of the noise. As for noise floor now you would think you were listening to a $2500 tube amp. Sitting next to it you could see my IFI micro Black Label DAC amp. I have the DAC use as a preamp into the darkVoice that really cleans up and add clarity to your source . At the same time I have my HD 650s plugged into the IFI AMP. Two people can listen at the same time with the set up or I could play around between tube in digital simultaneously listening to both sources . I have nearly 100 tubes for DarkVoice and only one hums. If you're having such problems with all your tubes humming maybe you better start looking elsewhere for the source of the noise. When you start building tube AMPs for yourself your wallet starts hurting.

The question is: Who made the tube? VSI (who are they?) is most likely a rebrander.

Here it is. Sounds balanced vs. the Tung Sol. Still getting rid of my Tung Sols left hum. Taking longer than usual now at my 90th hour

Usejimmy:

I don't know if they are the same that Woo Audio is selling. I can say I have purchased one from that Seller and the Tube was in mint condition, quiet, powerful bass and great soundstage.
