6N1 6N1P E88CC NOS Gold Grid hifi Valve Amplifier Preamp fits Yaqin tube amp

The version of the 6N1P offered here is a superb NOS (New Old Stock) Soviet version with Gold plated Grid wires. As used in the popular Yaqin hifi amplifiers, but much superior quality to the Chinese valves supplied as standard with those amps, so a very worthwhile upgrade.

Near equivalent to E88CC or 6922 valves but with a higher heater current. This valve is used for the preamp and driver stages of the hi-fi amplifier model MC10-L by Yaqin, as the driver valve by Audio Research in their VS55 and VS110 amps and in the balanced input stage of the Almarro Reference Monoblock A340 amplifier. Also a very suitable replacement for the 6N1/6922 used in the Rode NTK and K2 microphones.

Current stock was manufactured by ORZep in the Orel plant in Russia in the 1980's, but responsibly sourced / purchased from the Ukraine.

Features include very low distortion and medium gain ƒ??optimized for line stages, internally shielded between sections, allowing its use at differing signal levels, higher anode voltage and dissipation rating than 6DJ8 types and larger cathode than 6DJ8 types, giving it longer life and more transient current capability.

A great value high quality double triode also suitable for use in any high end stereo designed around these particular valves. Note that these valves may need some time to burn in for optimum performance and will improve in performance and benefit from reduced noise / hum after the first ten hours or so in use. This is apparently sometimes due to hum transfer from the heater to the cathode which fades away as the heater forms up with extended use and is a known peculiarity of these valves.

Testimonial from the web, with thanks and acknowledgements;

''The 6N1P has a huge cathode and is known for its very high linearity....few audiophiles will find much to complain about with the 6N1P's low distortion and characteristically superb musicality and tonal balance.''
