Description


This high quality beam tetrode tubes used in output stages of low frequency amplifiers.

The 6P3S output beam tetrode are miniature devices enclosed in glass bulb and are provided with a octal (8-pin) base, rigit leads and an indirectly heated oxide-coated cathode.

Best Quality, the Sound is nice - authentic vintage tone. Long-life no less than 5000 hrs.

The accuracy of matching a pair no less ±95%. Matched with our HI-END tube tester L3-3.

All tubes new, military equipment and have "OTK" mark. Near equivalent: 6L6, 6L6GT, 6L6GC and 5881.
The tube is manufactured by the Reflektor, Saratov, Russia. Have date codes of 196x years.
