TEENAGE ENGINEERING EP-133 K.O. II Broken

Slide Potentiometer (Fader)

The fader's internal wiper or resistive element has been mechanically compromised due to axial or lateral impact. This specific component is the primary failure point in the 'Fadergate' phenomenon, where the shaft's connection to the internal carriage is severed or bent. Replacing this component restores the analog-to-digital control signal required for the 'EP' series functionality.

EP-133 K.O. II Replacement Unit

Because the fader is soldered directly to the main PCB, Teenage Engineering often treats the entire device as a non-serviceable assembly for consumers. If the unit is under warranty, a full assembly replacement is the manufacturer-prescribed solution for structural fader failure. This bypasses the need for high-precision micro-soldering on the sensitive circuit board.

Protective Fader Guard/Case

Secondary support components or third-party reinforced cases are often used to prevent a recurrence of the failure. These items address the root cause—lack of structural shielding—by providing a mechanical buffer that prevents external pressure from reaching the fader shaft. This is a preventative measure rather than a repair for a currently broken unit.
