MATCHED QUAD 6N8S NEW IN BOX 

SAME DATA CODES 1960-67

The 6N8S double triode was designed for amplification of low-frequency voltage. 

Tubes were manufactured in FOTON plant (TASHKENT City). 

Equivalents to the 6SN7, 1578 (very close to legendary 1578 tube with metal base). 

This tubes were tested on high end russian military tube tester  by a qualified engineer!
