Made by Reflector Corp, Saratov (1992).
Packing : OEM
There are two designs of this tube : one has
box-shaped plate,
consisting of two Pi-shaped halves, closed on all four sides.
These tubes were marked with Reflector logo.
The other type has a Pi-profile plate,
missing one side so the grid/cathode assemblies are visible.
This tubes have closed plate = see the photo :
Special Quality tubes use letters E or B ( or
both ) after fourth element.
E for long - lived ( up to 5000 hours and more ) tubes.
B for mechanically improved tubes.
The label OTK on the surface of the tube bulbe means that
it is a Russian tube was gone under a military test.
OTK is an abbreviation in Russian language.
It means: it was controlled by a Military organization.
The NOS 6N23PEV (6N23P,6N23P-EV,E88CC,6922)
Russian vacuum tubes have been checked by a calibrated Hickok 539B
vacuum tube
tester.
By the operating manual of the tester the typical value
of the MC (Mutual Conductance) of the NEW
6N23PEV (6N23P,6N23P-EV,E88CC,6922) vacuum tube is : 10.500
This is taken as 100%.
(Given for each tube System 1 and System 2 [in Micromhos]).
On each tube I placed a little white sticker with the measurement results.
MUTUAL CONDUCTANCE TEST: here we can get exact
numerical value in micromhos.
The condition of TUT (Tube Under Test) can be expressed in percent.
For example : in case of the NEW 6N23PEV (6N23P,6N23P-EV,E88CC,6922) listed typical
value of mutual conductance is 10.500 micromhos.
If the TUT has 11.000, the percental condition is
(11.000/10.500) x 100% = 105 %.
Result of the mutual conductance test, as follows :
