The 6N1P Box Plate tubes from 1960's is now very rare, and produce most accurate balanced smooth sound, with excellent detail!
The 6N1P Russian: 6Н1П is a Russian-made miniature 9-pin medium gain double triode vacuum tube intended for use as a line audio amplifier and cathode driver.

Basic data:
Uf = 6.3 V, If = 600 mA
µ = 35
Ia = 7.5 mA
S = 4.35 mA/V
Pa = 2.2 W

The 6N1P has similar ratings to the 6DJ8 and in the past was sometimes re-branded as such, however differences between the two types (the 6N1P requires almost twice the filament current and has only one third the S value) mean they are not directly interchangeable.
The S is about 4.35 ma/V, the 6DJ8/ECC88 has a S of 12.5 ma/V and a gain of 33 and a lower internal resistance.
However, the 6N1P is typically more linear for a given load.
It is therefore inaccurate to say that these two tubes are identical.
The closest western equivalent to the 6N1P is the well known 6BQ7A.
A ruggedized/extended ratings version of the tube is designated 6N1P-EV (Russian: 6Н1П-ЕВ).
It has currently found a use as a driver tube in hi-fi tube amplifiers (such as Audio Research models VS55 and VS110) because of its excellent low distortion and low noise characteristics.
These tubes were manufactured by the "Voskhod" plant in Kaluga, Russia

6N1P is considered to be the most balanced tube made in its category
and the 6N1P Box PLATE is considered to sound the best out of any of the 6N1P tubes.

6N1P Box Plate from 1960's is now very rare, this one should produce the same balanced and smooth sound, with detail and alive

These tubes produce the highest quality sound and are considered quite zippy!

These are all NOS (New Stock) new tubes, from early 1960's, and they were tested and checked and have quality check stamps on each of them.
Every 6N1P tube should have a pure gold plated filament
