I have an EH 6992 gold pins would that be better ? and what should I fit to better that ?

thanks in advance

thanks for that have picked up a mullard  

I hope you ordered from somebody such as Jim McShane, who will test the tubes competently before he sends them. Oh well. Try them out. I am sure JJ makes more good than bad; just their failure rate seems high. The power tubes that JJ makes are better than their small signal tubes. I have a JJ 6922 pair and an EH 6922 in my office CSP2 unit. These tubes are fine and have lasted around a year so far.

The 6N23P-EV if I am not mistaken is the same as the Electro Harmonix 6922. These are regarded as very quiet. That is why they are recommended for that input position. The EH 6922 I have in my home CSP2 is microphonic but that does not seem to be a problem.

I never bought any 6N23P-EV tubes because the prices seemed ridiculous. I am over the 6922 bug. I have had a Mullard 6DJ8, Seimens PCC88 but I sold all of them. The 6DJ8 is simply not an optimum sound and something was just not right with the PCC88.
 
Going forward I am sticking with the JJ E88CC (6922) the EH 6922; maybe some JAN Sylvanias 6922's and 7308's I have accumulated; but nothing made after the mid-1970's.  The Phillips "last gasp" 6922 tube production was just not very good. I have personally encountered a lot of dead and dying ones.

Good ieda.  I find it really takes 100 hours or more to truly evaluate all the paramters of a tube/get a new one to break in.

Not sure what brands or vintages you might have been referencing RR, but I did notice that the 6N23P-EV can be had fairly reasonably. Cryoset has them at $24, which could add up fast and seems to be on the high end, but I noticed on fleabay that they can be as low as $8. This lot is about $14 apiece.

I bought those Reflektor 6N23P-EV tubes from cryoset, and gave them a long chance in the Torii, and while stunning on some material, ultimately it was too crisp and tart for me. I like a more forgiving tube for use with all my material, and that one wasn't it.

I put them into my second Torii, the Mk II in my bedroom system. There less than ideal placement makes the system a bit too warm, and so far they're working well to ameliorate that.

I guess I'm not recommending 6N23P-EV unless you really like a lot of air and a far from a romantic sound (as Gopher uses the term, a use I agree with and a sound I like).

Full circle!

I've just got to have a 6N1P in my Torii, it's the tube type I keep coming back to. If I were using analog sources I think a 6922 might work, but with digital sources I find the 6N1P has the warmth and just a tad of smoothness most of my cds need.

Well, on these enthusiastic recommendations, I will keep my stock tubes close at hand.

You could try a 6BQ7. They are electrically similar to the 6N1P and are dirt cheap.

Thanks for the "nudge"...

I've been reading, but haven't had any time to post. Hope all is well with everybody. I tried that tube and came to the conclusion (as well) that it was a bit too detailed for my current system. VERY good option for the price though. The 6N1P still easily stands out for me as the best sound.

I've tweaked my digital front end a bit and while I originally felt the 0D3 was the best option, I've since settled on the 0C3 and have tried different varieties. My favorite is a 1940's pair of RCA 0C3's. The others I've tried are CBS-Hytron 1950's, Raytheon 1960's ?, Westinghouse 1960's, Sylvania's. All of those tubes affect the sound differently. I suppose I'd call it the "forwardness".

My last endeavor will be to try the 0C3A tube. This is the straight sided RCA 0C3 and should be very close to the coke bottle. The main difference is the voltage sag listed in the specs (I think). The voltage sag may be a good thing though....

Finally, I think it was Pale that mentioned the 1960's RCA rectifiers. I agree that for a warm, full bass they are without peer. I'm stocking up as well.

 

Well, the 6N1P is back in place. The 6BQ7 was an interesting listen, but ultimately it was less open and deep sounding and I missed that sound the 6N1P brings.

I want to ad a tube that I want to find more of but cant. a few months ago I picked up 2 Sylvania 6dj8"s that were made in the USSR. Are they  6n1p's, 23's ,,,,,,,dont know , i know they sound great , after going through the realm of 6dj8's . any comments ????????

thanks Rivieraranch, even the Sylvania box says made in USSR. When I bought them on ebay the guy said that they were rare. i ordered 2 n23's ,so i'll look them over with a fine tooth comb to see how close they are. I guess thats the only way of knowing

well fella's got my 6n23's , not a bad tube ,got to give it some break in time ,not the gold pins that are  so expensive . alittle forward , but not offensive . more like a real instrument would standout. liking it. ?????

I believe that the 6N23P is very similar electrically to the 6N1P.  I tried a cryo'd pair out briefly in my Torii, but ultimately much prefer the 6N1P for my system and material. May pop them in again one of these days or see how they fare as the driver section in a CSP2 or CSP2+ , , , ,

To be honest, the cryo'd tubes I most value and have used the most, the "super cryo'd" tubes from cryoset.com, I may enjoy so much because of the choice of the tube itself. They certainly are a type/brand of 6N1P I haven't had in a non-cryo'd version, so I can't really make direct comparisons.

I do think there may be some improvement from the process that shows up as sonic benefit. I have an open mind about it. One benefit I do think more than probable is longevity. Several sets of cryo'd tubes I have seem to have lasted longer than non-cryo'd versions. I want to say that there are slight tonal improvements in cryo'd versions too, but they're not huge if they're not imagined. . . . .

I don't think so Donnie. At least let me put it this way: there doesn't seem to be audible changes along those lines.

I'm not a scientist, but my reading along the lines of cryogenics makes me think that is not the case.

Cool. If you're using 6N1P tubes, cryoset.com's super cryo'd version is an excellent tube.

Yes, but what is the temperature differential between that of operation in a vacuum tube and arc welding?

I really doubt that the temperature in tube use would re-alter the crystal structure. May be wrong.

Again, my favorite cryo'd tube I haven't used in a non-cryo'd version and I may appreciate this tube for its natural qualities despite/beyond any changes from the process. But I tend to believe what I've read about the cryo process.

I'm sold on the 6N1P as well. I've decided not to stray from it. Great tube in these circuits.
