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.

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.

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.

7189 tubes with 274B


I changed from SV83's and 5U4G's to the Preferred Series 7189's and Preferred Series 274B's in my amp with great results. I was leary at first about the 274B since there isn't a data sheet and the only one I could find was the old western electric. I Emailed Jon and he assured me they would work fine, Well he was right. This combo has expanded my sound stage with great intensity at the edges and has the sound moving down my walls. The vectoring is beyond what I was expecting. Job well done Jon!

Rocks my Vox


Just got a quad today for my Vox AC30 and I couldn't be happier with the sound. Have a set in an old, green board Blues Jr I did most of the BillM mods to and they're great in it as well. It's hard to find musically superb EL84's that can also take the abuse of an AC30. The burn-in, then matching thetubestore does on these hard to find, premium military-grade Reflector 6P14P-EV 's is what sold me. Well worth the cost.

Great tube


I replaced 2 JJs in Blues Junior and got just what I was looking for. A little darker sound and smooth tone.JJs are pretty good tubes too, but I mostly play clean jazz and JJs had a more rough edges. Probably better for rock and maybe blues. I have Ibanez with PAF pickups and love my sound now. My Blues Jr is stock except I have a Cannabis Rex speaker.Although I only play clean, I cranked it up just to see what happens. WOW! So smooth, with lots of sustain and warm!Great tube...
