We have a Wide Range of NOS (New Old Stock) Vacuum Tubes for Sale. NOS means they are from former Factories c.1960 – 90s and never used. They are generally considered superior to new tubes due to build and materials which are no longer available.
Because our Vacuum Tubes are fully tested and matched in the UK, they offer excellent sound improvements, top quality and long life.
Built to a very high standard using scarce materials such as gold and platinum, our Vacuum Tubes are the original USSR spec and can be used as direct replacements for many modern amplifiers as an Upgrade Path. For Chinese Amplifiers you can also browse our ‘Vacuum Tubes by Chinese equivalent‘ section for peace of mind, or even ‘Vacuum Tubes by Amplifier‘.
