What are NOS tubes?

Welcome to PM Components New Old Stock site. 

PM Components has for more than 30 years supplied 'current production' valves and components to leading amp manufacturers.

 'New Old Stock' or 'NOS' is the term used for new, unused valves that are not currently being produced.   PM has been a regular supplier of such valves to meet customer requests. 

At long last we are in the process of cataloging and photographing our stocks; but with over a million valves in stock, this is not an easy task, so please if you can't see what you are looking for -contact us and we'll take a look for you.

We will only supply valves that we are 100% sure are genuine and unused.
