Yes, very similar.  Maybe some slight differences up top...?  Tough to say.  Are there differences in their specs?

Thurston do you think e88cc Siemens for  $99 cheap?

The only construction difference I notice is the 6N1P-E has a spring tensioner attached to each cathode, whereas, the 6N5P does not. These are often employed on tubes to reduce vibration and microphonics. Looking at the data sheets, these tubes ares slightly different, most noticeably, the gain on the 6NIP-E is about 35, compared to about 27 for the 6N5P. But otherwise, to me, they are more similar then different.

 

Both work fine in my amp, but then my amp is nowhere near as picky as a Lyr. So it is necessary to wait until someone with a Lyr trials a pair of 6N5P's before we can know if they are worth chasing after.

If they're from the '60s, yeah.  Well, maybe even early '70s that's a good price.  My limited knowledge of the differences comes from a post in the Tubes Asylum (I think; I've referenced in this thread) that details the five types that are commonly available, and which are the most desirable (YMMV, of course).  And prices from sellers who know tend to follow that listing.

 

If you've got a link, post it, or PM me, if you're trying to be sneeky! ;)  I promise not to divulge, as I have enough... Siemens.  Not enough tubes.  No, never enough.  For example...

 

I went looking for differences between the 6N1P and 6N5P, found this doc

 

http://www.4tubes.com/DATASHEETS/Russian-Tubes/6n1p-all-versions.pdf

 

read this:

6N1P is available in three versions.


1. Standard. Which al already much tighter specified as ECC88.
2. 6N1P-EV (or called EB, that is the same). Long Life. 
3. 6N1P-IV. A very rare version with very tight gain specification

 

(I dunno about "rare," as there are lots of 100 tubes available.  But whatever)

 

and immediately went to eBay, where my fingers took over, and before I knew it, I'd bought a pair of 1972 6N1P-VIs for $13 and change shipped.  Oh yeah, I got the bug... bad :D

Interesting.  Thanks for the insights.  Didn't Bob mention his 6N5Ps had arrived?  As noted earlier, mine are sitting in the post office until Monday.  No doubt they'll need a Deoxit soak, and then some Gold brushed on, but hopefully Tues. or Wed. I can fire them up.

Here's an interesting listing:

 

http://www.ebay.com/itm/MATCHED-PAIR-ECC88-6922-6DJ8-E88CC-TESLA-NOS-/261509342983

 

Says ECC88, but pictured are E88CCs (KR = July 1966 and AJ = April 1967 pictured).  Multiple lots available.  I really like the Tesla E88CCs I have, and paid more than that, certainly.  Might be worth an inquiry for some clarification, if anyone's interested.

 

Cheers.

I receive the 60's 6n5p

I forget, did you roll them yet?

post #3115 of 3118

 

If you got what's pictured, they're 'A' frame getter from June 1971 and March 1972 (3rd pic shows the stamps well).  Note this mistake from the description:

 

Both whit silver shields, A6/20 and A6/1F-codes on a
Small metal plate inside the tubes, o-getter and gold pin ,
See pictures,

 

Yes, it looks like an 'O' in pic #4, but there are no month codes past L (12th letter, for December), and pic #3 shows it quite clearly.

 

Hopefully they match up well and sound good.  I'd say $99 is a pretty good deal, esp. if they're really NOS.  I don't know if the $150 I paid for January 1963 Siemens E88CCs is worth the extra $50, but I'm just going to tell myself I got a great deal ;)

Not yet, I'm still burning Telefunken ecc189, now 50+...50 more to go...

Saw those.  I think it's odd that E88CCs have steel pins, not gold-plated.  Those are marked "IJ" which is September 1982.  Maybe that date explains the pins.  Also, the '37' factory code may or may not be more desirable than ones from the '32' factory.  I'd be far more inclined to take a chance on the ones I listed a few posts back (a Romanian seller with a ton of feedback).  They're from the '60s and are basically the same price.  Mine are from the '60s, factory code '32', and I really like them.

 

Here's the link again:

http://www.ebay.com/itm/MATCHED-PAIR-ECC88-6922-6DJ8-E88CC-TESLA-NOS-/261509342983

 

You can get Tesla date codes here, provided the tube is marked with the two letters:

Hope that helps.
