Obsolete and Aftermarket Components & Parts
Manufacturers & Services

SecondHandRadio.comAs the rate of technological advances increase at an ever faster pace, obsolescence occurs at an ever increasing pace, too. In highly critical areas, some manufacturers continue production for replacing worn out or failed parts. In most instances, production by the original company is halted after a short and another independent manufacturer contracts to do the job. Other companies design and produce their own form/fit/function substitute components, and still others rely on buying excess inventory to supply the needs of legacy systems. This page is a collection of sources for such needs.


My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks. Your best bet is to use a search engine to find company websites directly. If you are interested in advertising, please visit my Advertising information page.
