The Harman/kardon Rabco ST-7 is a linear-tracking turntable introduced in the mid-1970s, designed to offer improved tracking over traditional pivoting tonearms. It featured a sophisticated tangential tracking system that aimed to minimize the distortion and wear typically associated with conventional designs. The ST-7 was built with a complex mechanical structure, utilizing two electrical motors to control the movement of the tonearm, which allowed it to follow the grooves of vinyl records more accurately. This model was later produced under the Harman Kardon brand following their acquisition of Rabco. Despite its initial popularity, it faced reliability issues that affected its long-term adoption. Users noted the ST-7’s need for careful maintenance, as adjustments were crucial to its operation. Key to its functioning was the use of proper cartridges and alignment, with the Shure V-15 Type III often recommended for optimal performance. The ST-7 boasted impressive sound quality with good speed stability and minimal rumble, though some users remarked that it sometimes lacked weight in the lower registers compared to more modern tables. The aesthetic design of the ST-7 has also been appreciated by users, contributing to its legacy as a visually striking piece of equipment.
