12AU6 NOS Preamp Vacuum Tube (New Old Stock)
What Does NOS Mean?
NOS stands for 'New Old Stock' and refers to tubes that were manufactured years ago that have never been used. It can also refer to tubes that are no longer in production.
NOS tubes are often more expensive than current production models due to the fact that many tube models and types are no longer being made; these tubes are becoming harder and harder to find.
Though we do not sort our NOS tubes by brand, all of our NOS tubes are all USA or Western European brands. If multiple tubes of the same type are ordered we make every effort to give you the same brand.
