Reflector 6H23p-EB / 6922 (Premium) Preamp Vacuum Tube
From Wall Of Sound: "The 6H23p-EB tube is refined, restrained and nuanced. Starting with the bass, the 6H23p-EB is slightly less forceful, but more controlled and articulate than the Tesla ECC88/JJ E88CC combination. The midrange is nicely detailed. Male and female vocals are more present and detailed as well. The twang of guitar strings in Knopfler’s Golden Heart is more apparent. This increased detail is not at the expense of treble smoothness : it’s nicely detailed, yet doesn’t seem to overemphasize the vocal sibilance of the McLachlan and McKennitt tracks. There is, on occasion, a very slight treble hardness, but this is a minor failing in light of all the things this tube does well. I have about 90 hours on these tubes and it would not surprise me if this would smooth out a bit more by the 200 hour mark. The price is reasonable for the performance offered, and certainly seems like a bargain compared to the high prices and questionable performance of some of other NOS tubes...I wasn’t expecting the 6H23p-EB to be this good."
This premium Russian built NOS 6922 tube replacement is also known by various Russian names, including 6N23n-EB, 6H23N-EB and 6N23. These are the hard to find NOS (new old stock) of premium quality in both sound and construction.
The 6922 / 6DJ8 tube type is equivalent to the European ECC88 / E88CC tube and can be used in any 6922, 6DJ8 or ECC88 circuit.

Excellent tube lasts forever
by Scott
I echo Jack below to a degree. These are fast, detailed, neutral, upper-mids neither bumped up or rolled off, a clear step up in all ways from EH and most new production tubes. But it's not expansive and lush like a Tungsram or super-pure like a Telefunken of the best Philips. The bass if tight and dynamic, but not at all bloated or boosted. I wouldn't call it lean, but to some it could be clinical. Mix these with a warmer tube if you must. My 6-tube preamp nirvana is Reflektor + Telefunken + Tungsram.
I should also add these last forever, a good thing cos they're getting pretty hard to find. My pair has been powered on since 2007, and sound only *slightly* less-crisp than brand new ones I just scored.
Amp takes flight
by Paul
I was sceptical about the price. When I rolled this tube into my amp, it's like it took flight. The classical was detailed, rock was clean and bright, blues growled and the twang of bluegrass became 3 dimensional. I was directed to this tube by the staff, really in the know and took the time to explain things to me (tube amp newbie). Not a hit of distortion from my hi-fi (oppose to the stock Chinese tube). Hope that this tube lasts a long time, the sound is spectacular.
Great tube but only a pretty good NOS
by Jack
When comparing the Russian Military 6H23p-EB tube against production tubes, this tube is truly something special. But against other good NOS tubes in this price range, it depends.
The best thing about this tube is its transparency, speed and three dimensional soundstage.
The tube sounds very linear. It has a really tight and controlled bass, but compared to some NOS tubes, it can feel a bit lean and clinical. The mids are better but still lacking warmth. The highs is where the tube really shines.
Listening to this tube reminds me of listening to a Siemens CCa, it is fast and tight but lacks a certain substance or euphoric feel.
This tube would be a good complement to an overly warm setup, but if you're looking to make your setup warmer, there are much better NOS tubes out there.
Durable, nice sounding tube
by Jeff
Been using these tubes in an Audible Illusions preamp. The sound is lush and detailed with a clean treble and a tight, tuneful bass. Also very reliable.
