Our Preferred Series 7189 tube is a versatile high quality option for EL84, 6BQ5, and 7189 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.

Fantastic in a Boogie TA-15 - made a good amp fantastic

These tubes took my Boogie Transatlantic TC-15 to a new level. They made the amp more airy and improved transients. Clean tones chime more, gain tones are richer. Transient response is significantly improved. All harshness is gone. Increased overtones. This set re-voiced the entire amp in all the right ways. Outstanding upgrade for a EL-84 amp

My new favorite EL84!

I am using a pair of these in a Cayin HA-1A MkII headphone amp. I have a lot of NOS EL84s for this amp including RFT, Polam, Tungsram, Brimar, Mullard and so on. I also have your typical offenders for current production tubes like EHX and Gold Lion. These are as good as the any of the best of these mentioned or not mentioned. I would say these and the Polam are my favorite, but knowing that these are easily sourced and at this price is remarkable. I am getting very good details from these. It's almost Triode power stage level detail out of a pentode! Also, probably the sturdiest looking/feeling EL84 that I've seen. Very impressed at this point and considering a backup set just in case these do become scarce or in case they change to a different tube for their Preferred EL84. I would recommend these to anyone. NOS tubes of this caliber at this price are few and far between these days.

Why are you reading this? Just buy them!

As an AC30 owner, I'm always on the hunt for a robust EL84 type tube. I've tried the new production offerings from New Sensor (EHX, Mullard, Tung Sol, etc.), JJ and even a few from Psvane. They never lasted long and the tone was inconsistent.

Enter the Preferred Series 7189. As many have already noted, this is an up-rated EL84 designed for higher plate voltages and power handling as well as being made to withstand a nuclear blast. Pretty sure I could take one and subject it to a 2 meter drop and still be able to use it without worry (though this isn't recommended by the manufacturer).

As for the sound, you get tight low end (I actually found I had to dial back the bass on my 30), strong mids and clear, well defined highs. You also get more clean headroom so you get to push your amp a bit harder before breakup.

All and all, probably my 3rd favourite EL84 type behind the 6P14P-ER and the 7320. A solid performer when you need it.

These blend the best of all the good parts of 6BQ5/EL84s and I just love them. I discovered these in 2007 & never looked back.

I discovered these around 2007. NOS USA 6BQ5s seemed rather dirty sounding, compared to a Mullard or a Philips EL84. Seimens made a delightful EL84. Telefunken invented these things and the Telefunken is the cleanest most clinical EL84 ever made. The Soviets somehow blended enough of everything into their 6Pi14EV to make a tube that I feel delivers a little bit of everything from American 6BQ5s to the holy grail Telefunken and blended in the best parts of every one of them. I prefer these in a guitar amp over Telefunkens too.

Tone, Reliability…Meh


First pair were faulty and blew the rectifier and fuse. Second pair has some hours on them, but nowhere near 5000 hours. One’s already microphonic. Swapped them out for a set of JJ’s I had lying around (which I’m not a big fan of) and the amp actually sounds better. Go figure. Not as hard and stiff. Gave 1 star because these have not held up their end of the bargain and cost extra dough on amp repair and rectifier replacement. Plus, TAD, JJ, Mullard and Tungsrams all sound better. To my ears anyway. Amp is a TopHat Club Royale.
