Hi, can you please tell me what does mean that NOS? I see that NOS on meny titles over the wrold, does it mean = not over sampling ?? I would understand that it is called a "rare specimen", but I can't understand why it caled "NOS", what does NOS mean?
And more pictures about 2SJ74 V grade and a 10MHz reference clock.
