6n5P in CSP
12/16/17 at 02:38:12
 
I ran across an ebay ad for the 6N5P that claims it is the military version
of the 6N1P. What limited info I can find says that it is a different tube
though, so I thought I'd come here to the 'horses mouth' so to speak,
and ask if anyone has tried the 5P in their CSP.

I’ve never heard of such a tube. I would stay away from it.

I thought I had read about this tube form Steve so did a forum search. Check out his comments.

From this Link: https://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1510110956/0#0

"The TORII JR is designed to use your favorite 6922 input tube, one per side. The 6922 is fast, clear and dynamic.
We have shipped the amp all summer with a new Chinese 6922 tube called a 6N11. It is the fastest we have heard.

If we could get consistent results in a TORII JR from the 6N1P that would have been the tube of choice to ship the amplifier with because it is so warm by comparison.

A NEW TUBE OPTION for the TORII JR is the Russian 6N5P.  It has the warmth of a 6N1P with the clarity of the 6922. The tube has a touch less gain which helps keep the amp from getting aggressive sounding.

I will be shipping the TORII JR with these fine sounding input tubes while quantities last because as the designer of the amplifier, it sounds the way it's supposed to with this input tube, which is musical, honest and seductive.

This tube should also work in place of the 6N1P in any of our amplifiers  and pre-amplifiers too.

Steve"

"Re: New Decware Zen Amps - SE84UFO3
Reply #28 - 08/24/16 at 10:44pm   That is my maker's mark.  I have put it on several random products that have passed through my hands to see if it feels right, which it does.  The SE84UFO3 will be the first item to carry the mark from serial #001 on.  It's only fitting really, the amp that started Decware and here it is today in it's 20 year fruition having peaked out in this consistently simple form.

Interesting story,  I always figured if money was no object and you wanted to see how far you can take the fidelity of a Zen Triode using the 6P15P-EB tube it ships with, it would likely involve inter-stage coupling transformers to replace the cap between the input and output stage.  

This is where I learned (as usual) there are no consistent roads of assumption with this design, and for what the transformers improve they also actually take away.  I suppose the strength of the Zen is the very fact that it takes the weakest link in the circuit's signal path - the capacitor - and makes it the amplifiers strength.  It does this by using the effect that the cap has on overall phase angle in the fundamental voicing and output stage design to a point where like a fine piano, it is tuned... don't mess with it.

I have been listening to Dan's and my own pair break-in for the past few weeks and they are like magnifying glasses.  I have been playing with a variety of input tubes to get a feel for what the amp will bring to the customer. The input tubes include 7 expensive NOS 6922's, 2 outrageous 7DJ8 long bottles, 6 NOS 6DJ8's, several hand picked 6N23P, a few hand picked 6N5P's, and of course the stock 6N1P-EB that all Zens have shipped with not to mention the latest 6922 from Shuguang, the 6n11.

If we take all of these, the 6N1P is the juiciest. On the other end of the scale is the most pristine detail nearly to a fault tube, the new Shuguang 6n11.  It's resolution is exhilarating... with good recordings.  Nevertheless, the insane speed and resolution of that tube with several NOS tubes being possibly as good with overall perhaps better balance, the combination with the UFO output transformers is really a new benchmark.  Tonight it bested a system that should have laid it to rest.

Boy, this hobby just never gets old does it Wink

Thanks Will. Good to know. I have a pair of triple mica 6n1P's that I used in
a CSP2+, and plan on using in a new CSP3. I may have to order a pair of
5P's to try also.

Well, it turns out my 'triple mica' 6N1P's are actually mislabeled 6N5P's.
I used them in my 2+ version and liked them better than the stockers.
So I guess I had my question answered all along. Hah!

So, I've been researching this and my tubes may in fact be triple mica
6N1P's, not mislabeled 6N5P's. They look identical to pix of the 5's on
ebay though. Color me confused.

Hey funch,

FYI...
I have two pair of 6N5P and the construction is nothing like the 6N1P.  I’ll post pictures later.  The 6N5P’s that I have are 1961 Black Plates (supposed to be the best 6N5P) that I got directly from Russia with a plate structure very similar to the Siemens ECC82 Nickel Plate.

Tried them in my CSP3, Nice, but the Valvo PCC88/7DJ8 with 6N11’s are back in.  Lost too much speed and detail for my liking, always a trade off.

Cheers

Here’s another of the 6N5P.  In the first photo the left tube is the 6N1P that came with my UFO2.  All the 6N1P that came with the UFO2 and CSP3 are identical.  Not so the 6N5P.   Hope this helps...

That's exactly what I'm seeing. Your pic of the 5P looks exactly like my
triple mica '6N1P's'.

The thing is, some of the printing on my triples is silver, but the label
'6H1N-E' is in black.  :o

That’s a head scratcher all right.  All the 6N1P that I have, probably 5 that came from Steve, look nothing like the 5P.  What are the chances that its a mislabelled 5P?  I guess anything is possible, but I couldn’t confirm one way or the other.

What I can tell you is that the result from my 5P’s is definitely different from the 6N1P.

To add more fuel to the fire, I've been looking on eBay at 6N5P's. I've
seen at least two ads for tubes listed as 5p, with 6H5N printed on the
glass, but having plates like the 1P's. ?????????

I recently purchased these, but haven't paid for them yet.

https://www.ebay.com/itm/6N5P-AUDIOPHILE-LF-TUBES-BLACK-BOXED-ANODE-2-NEW-NOS-19...

They are labeled 6H5N on the tube correctly. The plate structure looks different than the 6N1P tubes to me. I searched for 6H5N with triple micas and black plates...

Those are 6N5P's. They are labeled correctly. 6H5N Russian = 6N5P to us.
They will work in the CSP.

Going to resurrect an old thread.  With looking to refresh and change up my CSP2+, I replaced the input stage from a stock 6N1P with a 6N5P, and the stock back pair stages to a matched pair of 1950’s smoked glass RCA 6SN7’s.  The rectifier is a PSVane 5AR4.  

My 6SN7’s were previously used as the input stages on my Zen mono’s….which are now replaced with a matched pair of gold grid Tesla 6922’s.  (still have to fire up them up, but that’s for tonight’s session).  

Anyhow…the 6N5P is brand new, so it’s breaking in, but the sound going through the Grado’s is engaging.  Nice warm tone with good detail.  Need more time, but there is a tad less gain than before, and the mid bass sounds slightly thick presentation, but no where near fat.  But…I can see that this combination can be good after break in.  The real test will be later when I fire up the mono’s and see how the Tesla’s sound.  This will be the first time I ever put Tesla’s in any of my amps…so I’m looking forward to it.  I have been sitting on these Tesla’s since 2021 when I started seeking out my white Zen’s.  

I’ll report back on the Teslas in a separate post in the tube section, but for now the 6N5P is great replacement from the stock 6N1P.  More to come.
