Audio Output Pentode
The Russian 6N14N / 6P14P Vacuum tube is an exact
equivalent to the American 6BQ5 and the European EL84
tube.
It is a double triode designed for low frequency power
amplification. They are miniature devices enclosed in a
glass bulb, provided with a nine pin base and an
indirectly heated oxide-coated cathode.
The 6N14N / 6P14P tube is used
in the output stage of audio-frequency amplifiers and is
also resistant to ambient
temperatures ranging from -60 to +70 degrees Celcius.
The service life for this tube is 2000 hours when new.
This particular group of tubes test very strong.
