Steve,

That's interesting! I want to try them just because I can, but what do you expect the doubling of gain at that point will do to the overall balance, sound, tone, power, or anything else you can think of in a Zen C?

Are these to be used in a CSP or Select in place of the 6922/6n1p/6bj8?

How about the Zbox?

Steve,

bump this thread when they comes it, I'd like to try it along with turning my CDP's output to 750mv.

rmt,

First, I would like to please have a confirmation from Steve that the 6N2P does indeed have twice and not half the gain of a 6N1P as my reading of the specs makes me wonder.

Steve - Have you actually compared the 6N1P with 6N2P (6H2N - Russian spelling) to hear the gain difference?

If the 6N2P does indeed have twice the gain of a 6N1P, it will make your Select compatible with some low output devices that can't drive the Select very well with a 6N1P.  Devices like low output customized CD players.  Also, if you use a pre-amp with low gain, it may make quite a difference in your LP listening.  What's possible are enhanced dynamics which are lost with lesser gain.

However, if you suffer no gain-related problems right now, I suspect you may find differences of flavor with this tube, but it will just be another tube to try among many others for what sound you prefer.  But if Steve says it's good, it is likely worth a go.  That's the fun thing about tube rolling -- it's generally fairly cheap and the results can be most interesting and every once in a while you stumble upon a tube that just seems right to balance the rest of your system sound.  

Dave,

I searched under 6H2N and found that this is merely the Russian spelling for what in our alphabet translates to 6N2P and the 6N2P is stated as being a replacement for a 12AX7.

However, I would be pleased to be corrected for sure, if I have made a mistake in this.  The tubes I just bought read "6H2N" on them, but were advertised as 6N2P.

Anyway, glad to hear from you again Dave -- I was away from this site for two whole years!  Very nice to hear from old friends again.  

Dave,

Good research and good news - glad to hear the gain is about 3 times that of a 6922!  I REALLY look forward to trying my new tubes once they arrive (first they go from Bulgaria to KathiCryo in Ohio and from Cryo treatment to me - about two or so weeks before I'll have them).  My dear Torii I amp returned home to me after being away for 2 years with another owner.  As it doesn't have the extra gain stage, the pumped 6N2P-EB (military grade) vintage 1974 tubes may be quite alot of fun as the gain was "just good enough" using a modded Sony 685 CDP.  However, I run my modded Torii Testarossa without any feedback and it will really be interesting to see what these tubes can do.  Yes, the amp is stable without feedback and sounds much better without it.  But I also have extra filtering in this amp in the form of dual chokes per channel, so ripple and interstage supply problems are about nil.  New tubes!  This should be fun!  Of course, if it's a dud with my amp, so be it, but maybe, just maybe ......
hope springs eternal --
