AMAZON multi-meters discounts AMAZON oscilloscope discounts To the potential electrical component buyer, designer, and professional engineer there are available a number of directories of sources for electrical merchandise. These directories, of course, contain sources for metallic rectifiers. However, the listings are generally mixed--no indication as to whether the source is for copper-oxide, selenium, or magnesium-copper sulfide rectifier. Worse yet, the listings generally contain references which are not primary sources for rectifiers but those who either purchase their rectifiers from primary sources and then manufacture rectifier power supplies or allied devices, and those who purchase the plates and assemble rectifiers to order. In the listings to follow every effort has been made to include only primary sources for metallic rectifiers. This type of information puts the potential customer in direct contact with the source and avoids delays and extra charges when special rectifiers are required. The first listing contains the names and addresses of these primary sources of metallic rectifier manufacturers. The second listing gives the names of the manufacturers of copper-oxide rectifiers; the third listing gives the names of the manufacturers of the magnesium-copper sulfide rectifiers. The fourth listing gives the names of the manufacturers of the selenium type rectifiers. The remaining listings indicate where specialized metallic rectifiers may be obtained. These specialized listings cover instrument rectifiers, valve rectifiers, high voltage rectifiers, rectifiers for radio and television receivers, and high frequency rectifiers. The writer has checked these listings very carefully and sincerely hopes that no errors or omissions are present but in a field which is undergoing change and rapid growth only a periodic revision can keep the listings up-to-date.
