Those kind of words are going to be subject to interpretation buy your speakers, your musical tastes, your associated equipment, your mood that day, and many more things that have nothing to do with the construction of the tube itself.
Get a few and try them. 🙂 🙂 🙂 I will say that the current production tubes, both European and Asian are surprisingly good.

Good to hear that the current production of 6V6's are fine and dandy. I have the Tung-Sol reissues from Russia and they seem very good to me. However, my former experiences with 6SN7's surely confirms that there are significant differences between tubes, like for example that Sylvanias are brighter than RCA's. Some sort of universal descriptions should still be possible as long as we don't talk about "good sound" or "bad sound".
I prefer the USA (or post WW 2 European equivalents) NOS tubes... Sylvania, RCA and all the other brands that were just rebranded major brands.
I believe the cathode / heater design and construction is far superior in the these tubes as well as the metals used for the plate and other parts of the tube.

Found a place to download Vacuum Tube Valleys issue 10. Much to read for those of us with interest in the 6V6 Index of /roehren/VTV
Salas, still working on my mez b1 but came across this thread. I have a tube regulated ps 300 volts @ 80ma with 12 volt filament supply. Could buy 12v6 tubes. Could this power supply work???? Thanks for any help you may give me. Bubba177
Can somebody list worthy 6V6 candidates with some sound descriptions to try out with this preamp? Please use words like fullness, transparency, darkness, lightness, extention, bass, midrange, treble, 3 dimentionality, dynamics and so on. The things I've read on the net almost always seems related to guitar amps, and it doesn't really tell me anything about the use in a preamp.

I wonder which preamp would win between this 6V6 preamp and the B1 Triode with Korg Nutube. But if the B1 is worse than the DCB1 and the 6V6 is better than the DCB1, maybe a hotrodded B1 triode would sound good.
The Korg B1 is probably the most "Tubey" (in a very beautiful and pleasant way) device I've ever heard.
And maybe sounds cleaner than regular tubes: YouTube
It probably sound similar and cleaner than this small tube, but the 6V6 is much larger and has a different tone. Anyone who heard both the Korg Nutube and the 6V6 preamp?
An old school tube preamp is beyond my capabilities so I might try to build a Nutube preamp instead.

Could someone tell me what the minimum voltage on the coupling capacitors would be??? Thanks bubba177
I have a transformer with two 18 volt secondaries. is this too much voltage for the filament constant current circuit? Thanks for any help
bubba177 - does it have dual primaries? You could wire it for 240v, and get 1/2 the voltage on the secondaries, and that might work... But I'd still put a decent size heatsink on the LM317's, as it still has a lot of voltage to regulate away (by turning it into heat)
It does but trannie also has b+ and rectifier. So that won't work. Right now i'm using lm7812 fixed with 12v6. Was trying to be able to use new tung sol 6v6 using the 18v filaments. Guess adding a small trannie is best option what do you think?
one secondary was only designed to power 3 12ax7's which is about 45ma I think, which is one 6v6. i have to use both secondaries one per tube
I know that it has been stated that the input Z of the amp receiving the signal from this preamp should be 15-20k, but how strict is that?
Can I run the 6v6 gain version, with 3uF output caps, 2ft max cabling, into the unbuffered version of this ncore amp with input Z of 5.3k ohms?
https://www.hypex.nl/img/upload/doc/ncore/nc1200/Documentation/NC1200_datasheet_R8.pdf
RC calculation says the roll-off is 10hz, and I believe the gain version output Z is 1.5k, so should be sufficient? What would be the negative repercussions if any?
If not enought juice, can I run two 6v6s in parallel?
