1578 / 6SN7 / RUSSIAN 6N8S / 1960's Vintage Vintage Russian Military grade 6N8S / 6SN7.
These Tubes were made at the Tashkent military plant in the former USSR. Date: June 1965. "OTK" marking, which indicates premium military grade.
I have been rolling 6SN7 and their varients for 12 years and these are among the very best that I've heard. Seems like I have tried them all (with the exception of the very pricey Tung Sol Round or Oval plate) These are very, very good in all regards!
These are unused NOS tubes.
