I recently serviced this gorgeous little Harman/Kardon T-20 belt-drive turntable.
Harman/Kardon, or H/K as they were known, made some lovely gear, all of it uniquely styled and much of it uniquely engineered as well. There are some quite desirable pieces out there and for a simple direct-drive vinyl spinner, this tasty little T-20 is well worth a look.
An FG (frequency generator) servo provides exceptional rotational accuracy in a modestly priced turntable. A pitch control lets you adjust for speed variations, thereby maintaining consistent accuracy. A high mass platter helps ensure that the accuracy is kept play after play, and a combination rubber/coil spring suspension located in the feet isolates the chassis from vibration. A low mass tonearm, capacitance trim, cueing, and anti-skating are all standard features.
