Here the idea is not to list all manufacturers of electronic, mechanical or electric parts but rather list those that either make devices specifically intended for AV electronics as in specialised silicon or components that are of a great interest to that field even if not specifically intended for it such as in the case of thermionic valves or high quality capacitors. In other words here go all manufacturers of audio devices not intended for end users but rather for producers of equipment, be that a multinational or a DIY hobbyist. A small number of companies are active in both manufacturing end user products and parts and in those cases they are either linked to from here or in the cases where they are distributed separately from the consumer lines they are listed both on this page and on the Hi-Fi & AV Manufacturers pages.
