Sixty years ago this month, the May 1959 issue of Electronics Illustrated carried a review for the then-new Eico 720 transmitter.
The reviewer noted that the kit could be assembled in a week of evenings, and was within the capabilities of the beginning kit builder. The set had a maximum input power of 90 watts, but the plate current meter had a red line indicating the 75 watt limit for novices, the kit’s primary market. The review noted that the transmitter ran cool, despite its compact size. The output filtering was especially lauded, as the transmitter was well protected against television interference.
The kit sold for $79.95, with the wired version selling for $119.95. The review concluded by declaring the 720 a Good Buy for either the novice or the veteran ham.
