I'm not too proud or vain to
admit that until I saw this advertisement in a 1946 issue of Radio News
magazine, I did not know (or don't remember knowing) that "Amphenol" is a compact form of the
American
Phenolic Corporation.
Phenol
formaldehyde is the technical name for phenolic.
Bakelite, the trade name
for polyoxybenzylmethylenglycolanhydride, is probably the most
familiar form of phenolic since it was used in many types of electronics for both
enclosures and internal component boards and the components mounted on them,
connectors, and more. Modern plastics, fiberglass, and resin compounds have
replaced most or all phenolic components. This particular promotion is
specifically directed toward amateur radio operators (aka Hams), who composed a
fairly large fraction of the magazine's audience. BTW,
Amphenol is one of the diminishingly
small number of American companies still around going by their original name.
Even more rare is that it appears to still be a U.S.-based concern.

Amphenol and Radio Amateurs Have Always Worked Together
Radio amateurs are the most versatile technical experimenters known - and so
are Amphenol engineers. Amateurs have pioneered the greatest share of electronic
developments since the dawn of radio - and Amphenol has pioneered in the development
of components used by hams.
Amateurs have an appreciation of the electrical engineering problems in the production
of components to give the best performance. They agree that Twin-Lead, pioneered
by Amphenol, is one of the most important and useful new products in the field of
electronics.
75 Ohm Transmitting Twin-Lead
Amateurs asked for it - now here it is! It's the new heavy duly 75 ohm Amphenol
Twin-Lead transmission line. Conservatively rated at 1000 watts for 30 mc or lower
frequency. Available - now - at your distributor's.
Receiving Twin-lead is available in 75 ohm, 150 ohm and 300 ohm impedances. Get
a copy of Amphenol's new Twin-Lead bulletin from your dealer.
