The NOS 6H23P-EB (Premium) tube is a very noticeable upgrade over the Sovtek 6922 tube and Electro Harmonix 6922 tube. They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions. They excel in detail, speed, and soundstage. The highs have air and sound natural.

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.

X Cans headphone amp


My headphone amp was sounding poor, noticeable back ground hum. Tested the tubes, well under min. spec. Tested the 24 electrolytic caps and found half were bad. I replaced all with high quality 105 degree c. caps. I installed these tubes based on their qualities. I listen with AKG 701's and on testing, this amp now sounds amazing. Highs are extended and brilliant, mids are rich, base is tight at all listening levels. Dead silent with no input signal. I will probably experiment with different tubes but these will be hard to beat. Well worth the effort to recondition this amp.

Russia's Finest


These tubes are the longest lasting. The quietest and some of the very best sounding 6922 EVER!

AMR AM-777


Best tube I have tested in this amp.

Incredible Quality - Long Life


My wife and I bought an Anthem Integrated 2 amp in 2000. These tubes, combined with Sonic Frontier's awesome engineering, produce incredibly deep sound quality. The original tubes are still working perfectly. I thought we'd finally blown one due to lightning nearby. I pulled and inspected both tubes - stunning workmanship. I cleaned everything and reassembled the amp and it is performing flawlessly again.

Huge improvement in my Grant Fidelity DAC


This little tube made more of an improvement in my system than any upgrade ever has. Started with speaker cables. Then preamp tube upgrade power amp tube upgrade, interconnect ext. This upgrade to my DAC did more than any of the others did. It tightened the bass dramatically clairity , presence, and soundstage took big leaps too. Never expected that, it was a pleasant surprise. Definitely gonna stock up on these. Best return on investment I've ever had for my system !
