Made by Tungsram (Hungary).
Packing : OEM.
The used ECC85 (6AQ8) Tungsram 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 ECC85 (6AQ8) vacuum tube is :
3.800
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 ECC85 (6AQ8) listed typical
value of mutual conductance is 3.800 micromhos.
If the TUT has 4.000, the percental condition is
(4.000/3.800) x 100% = 105 %.
Result of the mutual conductance test, as follows :
