Wollensak 2770AV
Not much is documented about the Wollensak 2770AV. What the record shows comes from classified ads of the mid-1970s, which call it a high-speed cassette duplicator - a "fast-copier," in the wording of the day. A classified listing in Audio (January 1975, p.76) offered a used 2770AV for $800. Similar "cassette fast-copier" listings ran in British trade classifieds from late 1975 through January 1977, which suggests the machine circulated on the used market for a few years.
No original manufacturer literature, full specifications or period reviews have surfaced. Production years, original price and technical details are not recorded in the sources available to the Archive.
