Vacuumtubesdotnet is the largest supplier of NOS tubes in the world. We have been in business for over 40 years and have over 10,000,000 NOS tubes in stock including 8000 different tube numbers. Whatever you need we probably have and will be happy to list for you. 

Everything we sell is tested on one of more of our 14 different tube testers, including an Amplitrex AT1000, both versions of the Maximatcher, computerized versions of the Hickok 118B Cardmatic and several other lesser known testers used mainly on obscure tubes that are nearly impossible to find a test for.

We guarantee every tube we sell for thirty days except for breakage, open filaments or operation outside manufacturer's specifications. You will be satisfied or we?ll make it right, right away.
