This four-track Hi-Fi stereo tape recorder Telefunken 204TS gained popularity not only among home users and amateur sound hunters, but also among professional technicians and eventually collectors. Its wooden casing with a transparent cover feels like a jewel box for analog sound. It’s a device that looks modest, yet is surprisingly powerful in terms of technology.

Unlike some of its competitors, it had only one motor, so the entire tape movement was handled by a clever mechanism of belts and gears.

Among collectors, it’s often referred to as a "tape recorder with character" – it may have its quirks, but when properly adjusted, it rewards you with sound that remains authentic, rich, and vibrant even today.
