I have a lot of 10 x 6p14p-EV unboxed NOS = $100
I will ship worldwide.
6P14P = 6BQ5, EL84 and 7189 tubes.
E = Extended or long life (>5,000 hours)
V = Mechanically ruggedized for low microphonics and reliability
6P14P-EV is NOS (New Old Stock) Russian 6P14P-EV as translated from Cyrillic. It is a military build that meets or exceeds the 7189 specifications.
