That's what i was worried about when i first started with tubes 2 years ago. And bought some from Brent Jessee who was very useful
 
But they are a lot cheaper on ebay.
 
You should be fine - just stick to sellers that sell a lot of tubes and have a great history - as in 99.8% success.
 
And you can always ask here or in the "Schiit Lyr tube rollers" thread or even in a woo wa2 thread about any experiences with particular buyers.
There are a lot of compulsive, addicted tube buyers that are always part of the thread - they probably call ourselves themselves tube connoisseurs, rather than addicts. They can usually give you some sound advice.
 
and of course you can always look for sellers with very strong histories that also accept refunds (listed on their items) if there is an issue. You also always have the paypal protection too.
 
at the end of the day i won't say it's 100% foolproof but by exercising a good level of caution you should be fine
 
anyway that's my 2c worth


Get access to a good tube tester if you buy off Ebay.  How do you know what you are getting otherwise? 
 
These Ebay dealer know you don't so can post any test reading they choose - and know that 99% of the buyers won't verify the tubes life left and/or quality.
 
Take it from a guy who has bought 100's of tubes off Ebay

  Ok Had a chance to do a little tube rolling ...
 
 
 
 
The best of the three the the Western Electric 396A with these inexpensive 6N3 to ECC88 adapters (thanks Terry!).
Rich harmonics, deep bass, nice detail - a true bargain for around $50/pr.

 
 
 
Cautionary note: The Lyr 1 HP amp is known to be able to handle a wide array of tubes - to that group I believe the WE 396A could be added (but check with Schiit first), as for other amps like the Lyr2?  Best to contact the manufacturer and ask them.
 
Cheers!

I now have 80 hours on a pair of these in the Mjolnir 2.
I have also operated with 6N3P-E and 5670W in Lyr 2, Valhalla 2, and MJ2.
 
This is not an endorsement of the use of any of these in the MJ2, Lyr 2 and Valhalla 2.  Proceed at your own risk, or not.  Ask Schiit.
 
YMMV & JMTC,

And how do you like the SQ?


In my quest to find tubes that bring my Sennheiser HD 650 to life, I would place these near the top.  I run the 650s balanced out of the Mjolnir 2 from Gungnir Multibit using USB and Apple Lossless.
 
Your statement "Rich harmonics, deep bass, nice detail - a true bargain for around $50/pr." is right on target, at least with the HD 650.
 
A surprise is that the Beyerdynamic T 1.2 single ended out of the MJ is responding well to these tubes also.  The treble is well contained and the bass is rich.
 
Have some GE JAN - 5670W NOS - 1988 that will go in the MJ next.  If they settle in as well as the 396A, a I have real bargain going :)

Good stuff!  Maybe try some vintage 6N3P's?

Does anyone have a single REFLEKTOR 75 "HG" for sale? I would like to have one to try out. Failing that, does anyone know where I might be able to buy one without risking buying from a Russian eBay seller?
 
Thanks!

These 2 ebay dealers sold me noisy tubes. Svetlana and JetParts. Stay away from them, maybe somebody here has a spare Reflektor. Do not think those 2 sellers test for noise or microphonics.

Wouldn't this one be equal to the 1975 6N23P? (though made in 74)
http://www.ebay.com/itm/2-x-6N23P-6DJ8-ECC88-MATCHED-PAIR-REFLEKTOR-Single-Wire-1974-SilverShield-/182400627190
 
Though it is from JetParts, not sure this guarantees noisy microphonics.
 
PS- I've already got my holy grail, just tryin' to help out others who are interested elsewhere

No, those are the 74 version. They finished in 4th place in the big review that is post #1 of this thread. I asked Bob about them and he told me that, no, they are not as good as the 75.

Yes I've personally been lucky enough to attain the '75 holy grail version thanks to the first post leading me there; but was under the pretense that the '74 version may sound the same being they appear to be identical internally. Guess somehow there may be a difference though between those.
 
Here's a couple photos of my 6N23P pair I've acquired, in case anyone wants to confirm these are the holy grail? 
 
 
 
  
 
I've yet the chance to hear these solo, but they're doing an immaculate job as drivers in my Elise OTL tube amp. I have the same as the version on the left of the photo lower right. They are a "Matched PAIR REFLEKTOR SingleWire SilverShield 1975 #4" from Svetlana_UA seller on eBay... and I've not noticed any noise issues in the month I've owned them.

Is this a really good Siemens CCa and worth more than a "normal" CCa or is it just a rare novelty that sounds no better or worse?
