Harman/Kardon T-20 Direct-Drive Turntable Service

I recently serviced this gorgeous little Harman/Kardon T-20 direct-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.

Features include:

Belt drive, FG Servo with pitch control
Semi automatic
Low mass, low friction, straight tonearm
Carbon fiber headshell
Spring-loaded rubber feet
Phono capacitance trim control
Vibration absorbent wood base

As a kid, I cherished my Tandy 200-in-1 electronics project lab, Dick Smith electronics kits, my Dad's hi-fi and my own first proper system. Later, I created Liquid Audio to help keep classic hi-fi gear alive and well. Our mission: to deliver TLC for classic Japanese, American and European hi-fi stereo equipment.
