Vintage Collectors Amplifier
This was the original magazine's catch-all category, and almost every post carried it. As a result it is the closest thing the archive has to a complete list: tube amplifiers and preamps from the 1950s and 1960s, a handful of solid-state pieces from the 1970s and 1980s, tubes, testers, a tube manual, and the company profiles the site wrote for each maker.
The span is wider than the name suggests. The oldest item is a 1921 Magnavox AC-2 battery amplifier; the newest are modern preamplifiers from Audio Research. In between sit dozens of American public-address and hi-fi amplifiers, the kit-built Dynacos, EICOs, Heathkits and Knights that put tube hi-fi into ordinary homes, and a smaller group of Japanese and European equipment.
If you want the same material organised by maker, the manufacturers A–Z is easier to browse. If you prefer to search, the amplifier index has a filter for model numbers and tube types. Makers with only one or two posts are grouped under other makers, and the notes on how this archive was restored explain what was removed from the original listings.
