Matched sextets and octets are available as well.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) Soviet Union era 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 or earlier 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.
