A Range of Upgrade Vacuum Tubes by Amplifier Make & Model.
We offer a great Range of Russian Military Tubes Upgrades for many East Asian Amplifiers!
Our Russian Military New Old Stock (NOS) Vacuum Tubes are carefully sourced Vintage Soviet Tubes.
These Vacuum Tubes are the original superior USSR Spec.
Because all modern Chinese Valve Amplifiers have cheap copies of these tubes, they thus benefit from such an upgrade. Our replacement tubes are a direct tube equivalent and thus offer better performance and longevity.
