I ordered 4 with the thought of swaping in the high-gain ones to compare (1 for CS and 3 for CSP).   Adding gain to the CSP might be an over-kill, but i look forward to finding out Smiley

I've listened to this new tube now for a few days and I really like it in my CS (Steve mentioned not to use this for the CSP). Using this tube I certainly notice more gain, but there is a bit more "umph" as well that I woudn't associate with just simply being louder.  Both vinyl and CD have more presence -  its a good thing Smiley

Works fine in my 84Bs but won't light up in my Taboo. What up?

Hey Jeff,

The Taboo uses a 12A_7 type input tube.  This new tube, as I understand it, is only to replace the 6n1P/6DJ8/6922 types, which your 84Bs use.

Steve says: Quote:
Using these in place of the 6N1P/6922/6DJ8 will add significant gain to the amp.
 Though he also says : Quote:
It is a 6H2N, Russia's version of the 12AX7.
, so it's a little confusing, but I don't think he means that it is a direct replacement for the 12AX7.  I could be wrong.

Hope that helps.

Scotty

I managed to score a handful of 6h2n (non eb/ev) and tried them in the Torii MK II.  At first listen, they seem like they have a lot less gain, but the soundstage broadens out and in some ways they seem to 'tame' the amp.

More listening later....

Greetings everyone

I was probably one of the first people to receive this 6N2P tube and have had some discussions with Steve on this tube.  Steve said that this tube is will not directly replace the 12A-7 tubes because the 6N2P has a 6.3V heater similar to the 6n1p/6922 tubes whereas the 12A-7 tubes has a 12V heater.  When it says that this tube is Russia’s version of the 12ax7, it means that the 6n2p tube would produce a sound that would be similar to what you would get if your amp was wired to use the higher gain 12ax7 signal tube instead of the lower gain 6n1p/6922 signal tubes.

Hope this helps clear things up a little.

Best regards,
M W II

Before I join the flock of 6n2p'ers, I want to hear from others who used it in their zen c. Right now I'm using a cryo'ed 6n1p which I think is absolutely fabulous.

But to have additional gain for the amplification is good considering my speakers' needs.

Kiss  There are tubes and there are TUBES!

Previously, my favorite tube in my modded Torii was a cryo'd 6N1P-EV of which I've shared quite a few here with other Decware fans.

I've done lots of listening and one gamble has paid off.  I bought four vintage NOS 1974 6N2P-EV with the bomb logo and marked CCCP, as well.  The construction is a little different than later versions of the same tube type.  Anyway, I had these four cryo'd and I then bought a stash of 16 vintage 1979 6N2P-EV which have NOT been cryo'd.

To make a long story short(er),  ::)  my 1974 Cryo'd 6N2P-EV are the best input tube I've ever heard, bar none.  I've compared this tube with the 1979 non-cryo'd version which sounds uncontrolled and honks dynamic changes, by comparison (but is still very good).  I've compared it with the legendary 1964 Siemens CCa which is great, but not as good as this 1974 tube.  I've compared it to the rare and wonderful ITT Lorenz 6922 of Stuttgart, Germany which comes in a fairly close second to the cryo'd 6N2P-EV, but the tube made at the height of CCCP power and prestige is simply more "you are there" real.

When judging a close call, my test is simply this -- which tube makes me want to listen more and why?  The cryo'd 6N2P-EV draws me into the music and declares the performers to be real and right out there in front of me more than any other.

So, if like me, you liked your cryo'd 6N1P-EV tubes as a previous best, go out and get the oldest you can find of the 6N2P, have them cryo-treated, burn them in for 100 hours and listen to the magic -- these tubes are my new ne plus ultra and by quite a margin over the 6N1P-EV cryo'd which were not quite as good as the cryo'd vintage Lorenz 6922 gold-pins.

6N2P-EV (EV stands for special quality and long life with lower microphonics, too) tubes can be found all the time on ebay from sellers in Russia and Eastern Europe for less than $5. each post-paid when buying at least 8.  Cryo treatment adds only another $5. per tube.

Anyone want some cheap Siemens CCa tubes? (just kidding - they will go on ebay for about $100. each as will the Lorenz and Valvo gold-pins).

Enjoy the music and get real, as in "you are there" REAL with some cryo'd 6N2P-EV - a real WOWSERS best in class.   Cheesy

I have cryo'd 6N1P's in my CSP. But it looks like the 6n2p is equivalent to the 12AX7 so it won't work in my CSP, but it will work as input on my TABOO which uses the 12AX7.  Am I correct here?

thanks for the info!

The 6N2P, while it has a level of gain similar to a 12AX7, the tube works like a 6DJ8, 6922 or 6N1P.  Therefore, it is a perfect choice to replace the 6N1P.  12AX7 tubes use 12 volts to light the filaments whereas all the other tubes here mentioned use 6 volts on the filaments -- the two voltages are not compatible, but this is no concern to our use.  Go ahead and try the oldest, cryo'dest 6N2P-EV you can lay hands on.  Give it 100 hours of burn in and you could be wowed beyond your expectations as was I.   Grin

Supposing you have a compatible heating source, could you not simply wire up a switch to allow you to switch between 6.3V and 12V filament heaters so you could use both?
I think I have seen something about this elsewhere, but I know someone here probably has a product that has said feature in it.

thanks Chas, now just watch the price skyrocket on your new favorite tube  :-X


seriously, any time a $5 - $10 unknown tube kicks ass like this is great

Mr Vaughn has his own "private reserve" list of unsung heros, many of which can cost less than the charges for safe shipping.  


BTW, there are other members of the 12A(_)7 family that can work very well in the Taboo, particularly if you don't need the full gain of the 12AX7.  I recently had a chance to audition one of the new anniversary style Taboos, and the sonic favorite of 3 input tubes we tried was an ancient Mullard 12AU7

Indeed, I do like the price on some of these signal tubes.
One such tip I got from him was about the AV7's, and by chance I was able to get the 2 which he suggested, and they are sweeeeet. And the shipping WAS more than 200% the price of each tube I got in that lot.

I have to agree, the older Mullard AU7's are something special, they are just so well rounded in their presentation, good for any and all types of music IMO. They also seem to interface good with the input stage on my T-Amp, which is nice, because it can be tricky to find the right balance.
