Our Preferred Series 7189 vacuum tube is a versatile high quality option for EL84, 6BQ5, and 7189 power tube circuits because of its clean headroom, power, dynamics and harmonic content. Please see John Templeton's review of this tube. This 7189 tube is rated for higher power and plate voltage plus longer life making it a premium upgrade for amps with tough operating conditions. The solid construction and heavy glass also minimize microphonics. For the hifi crowd, this tube is the perfect choice for Scott, Eico and Fisher amps. Our Preferred Series 7189 starts life as a NOS (New Old Stock) Russian 6P14P-EV as translated from Cyrillic. It is a military build that meets or exceeds the 7189 specifications

6P14P = 6BQ5, EL84 and 7189 tubes.
E = Extended or long life (>5,000 hours)
V = Mechanically ruggedized for low microphonics and reliability

We have been selling this particular tube for years but have found the production from the 1980’s to sound and work the best. We sought out and purchased as much NOS as we can find from this time period. They are then burned in, tested and matched on our digital high voltage equipment to make sure the tubes selected for you will provide outstanding tone and performance. The Preferred Series 7189 tubes carry a 6 month extended warranty.

HIFI lovers dream


These are definitive tube for any EL84 driven stereo amplifier. More power, more headroom, and clean. These tubes also handle a high plate voltage (370V) with ease as long as the bias current isn't too high. These are the best tubes I heard yet in my modded Glow Audio Two amplifier. One normally thinks tube amps with EL84's are wimpy, but definitely not so with these gems. I once thought NOS tubes were a gimmick, but todays tubes really cannot compare to these beauties. They stand up to everything at full power from heavy metal to boomy EDM without a single bit of distortion. Highly recommended.

This is THE 7189


I have owned and played trough tube amps for almost 50 years. I own hundreds if not thousands of tubes and my current amp, a very heavily modified EPI Valve JR, uses an EL84 power tube. I have used every EL84/6BQ5 tube that I have in stock and was never totally satisfied with the sound. Either the clean headroom was non-existent or the driven tone was bumpy or overly gritty. Today I received the PS-7189 from thetubestore. Removed the JJ EL84 I had been using (was ok) and socketed the 7189. WOW..what an incredible improvement! The clean headroom was there and the driven tone is smooth, strong, screaming. In this Single-Ended Class A Cathode Bias Design amp, with its hand wired board, Mercury transformer is the ultimate combination for me. I will have to order another before they are all gone. All this plus thetubestore's incredible service..can't beat it.



Have not had the opportunity to listen to many other EL84s in action as this amp is still quite new (hence the 3.5 stars), but the stock Groove Tubes (Sovtek) are considerably below-grade in tonal qualities to that of the "Preferred Series." Coupled with the addition of the 'BillM Mods' and replacement 'MOD Reverb Tank', I enjoy these tubes. A/B'd the GTs after mods and the "Preferred Series" win hands-down.

Just delighted


I put this into my Bugera V5 with the Preferred Series 7025 preamp tube. I have a new amp. I have always enjoyed the sound of this amp with a JJ ECC83-S and the stock whatever tube. I did not fool around and just re-tubed it with the Preferred Series tubes. I did not want to stop playing it. The inherent darkness has been eliminated and a much fuller tonal spectrum is available with the one tone control. For the sound I want, rich and chimey with delicious compression at low volumes to serious bark when the volume goes up, I love this tube. I see Tung-Sol now has an EL84 tube out. It is probably a great tube. This Preferred Series 7189 is superb. With sound like this the price is reasonable.

Works really well in Decware SE84ZS


Compared to the stock tubes (SV83) in my 2013 Decware SE84ZS, these provide much warmer sound, slightly slower but with greater amount of (or more noticeable) audible details. Wonderful tonality and "palpability".
