In 1982, Henry Engineering began manufacturing and delivering its first product: the Matchbox. This utility device proved to be a popular interface for balanced and unbalanced audio signals. In its original form, the unit delivered an audio response of dc to 20kHz ±0.25dB at 0.008 percent distortion with a S/N ratio of about 80dB.
After 25 years, Henry Engineering offers an updated version that fits in a 1/3-width, 1RU package. The current unit places the audio connections on the rear panel, unlike the original that provided all the connections on the front of the project box.
Henry Engineering reports that the Matchbox will be available in the original configuration in the coming weeks — just in time for its silver anniversary.
That was then
During the early days of radio broadcasting, it was common for stations to be owned by companies that could use the medium to supplement its other business. Department stores would own stations so they could promote the store and sell receivers. Newspapers would own stations to sell more newspapers. Even receiver manufacturers took up the practice. Powell Crosley is probably the most well-known for this with Crosley Radio and WLW in Cincinnati.
There was another manufacturer and station owner in Cincinnati that gave it a go. This 1925 ad from Popular Mechanics shows various Logodyne Big Five receivers available from the Kodel Radio Company, which also owned WKRC-AM. All of these units were based on a five-tube design and boasted fine hardwood cabinets, a built-in speaker and compartments for A and B batteries. Other models, including the Gold Star Series, were available with one, two or three tubes.
