Harman Kardon T40


A more massive platter and a larger, more massive base distinguish the Harman Kardon T40 from the T20.

An optically sensed auto-lift tonearm is incorporated, eliminating the return mechanism entirely and further minimizing unwanted tonearm vibration.

The high-loss (vibration absorbent) platter mat, made of a special high-density rubber, helps prevent vibration from travelling from platter to disc.

A disc stabilizer damps vibration and improves accuracy by reducing record movement.

The phono cables on the T40 are gold-tipped to provide excellent conductivity and low signal loss.

Belt drive, FG Servo with pitch control and speed lock

Working on the ST40 notes

I have one of these fine TT. One thing to note is that if you decide to take off the motor from the mounts, I found that the screws were way too short. Not even three threads could even be screwed into the motor holes. Another harder point of dissasembly is the slotted end screw that holds the arm on. Unless you have the right tool do not attempt to remove the nut. All in all, this is a very easy TT to work on. Now if only my ST-7 was so forgiving. lol
