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.

These tubes are incredible in my Friedman PT20


These tubes completely change the amp characteristics for the better. Notes went from saturated and fuzzy to really articulate and punchy with beautiful harmonic overtones. Also the amp can be turned up to higher volumes and still get good note articulation - great for playing with loud bands. Here's a video I made with these tubes in my Friedman PT20 amp:



I am amazed by these tubes!! I put these in a Peavey Micro Head, these tubes sound fantastic. In this amp it added a lot of bass it has been lacking, clear mids and plenty of chime.

Great treble/mid/bass balance


In my Vox Pacemaker—an amp I've found to be expert at exposing sonic flaws in tubes, guitars and playing technique—these 7189s won a shootout among six different brands, including the Philips ECG & GE tubes I usually prefer. Clear high end without any spiky or harsh stuff, detailed mids without graininess and warm but not tubby bass. My test guitar, a three pickup Rickenbacker 350v63, sounded terrific using all three selector switch settings. The neck & middle pickups together can get muddy through the Pacemaker (a fairly mid-forward amp despite its Top Boost-based tone stack) with some power tubes while the bridge p'up alone can sound thin & razor-y with others. Not the case with these tubes! Guess I'll have to get some more.

Very Pleased


Vox AC10C1 - have used Tungsol ei84s.( very nice tubes)....T.A.D. el84str's (nice tube but a bit 'sterile').....and now the Preferred Series 7189. The PS-7189 lives up to its billing\reviews. I am very pleased with this tube. Since getting these valves a week ago I haven't used my 2x10 external cab once as the Vox on it's own is sounding Better than Ever! Thanks Tube Store..This was my 4th order from the Tube Store and once again am Very pleased with service and products.



These are the best EL84/7189's I've ever used. A step above the Telam tubes, even. I've never met an EL84 that could do Bass like these tubes, and there aren't enough adjectives to describe how ideal the mids and highs are. I'm running these in a Fryette Memphis and it's never sounded bigger or better.
The Preferred Series from The Tube Store never disappoint!
