6N13S = ECC230 = 6AS7G tube. Matched pair
The 6N13S (6Н13С) double triode is designed for operation in electronic stabilizers.
The 6N13S double triodes are enclosed in glass bulb and are provided with an octal base and an indirectly heated oxide-coated cathode.
The 6N13S double triodes are ressistant to ambient temperature from -60 to +70C and relative humidity of 95 to 98% at +20C, as well as to mechanical loads: linear loads up to 15g, vibration loads up to 2.5g and impact loads up to 12g. Time life over 1000hr.
The accuracy of matching a pair no less ±95%. We matched our tubes on High-End Soviet Military Tube Tester L3-3.
All tubes new, military equipment and have "OTK" mark. Near equivalent: 6AS7G and ECC230. Very good sound.
