pioneer dj Pioneer DJM-300 Silver Fader Maintenance The internal parts of the vertical and horizontal faders have been cleaned. The fader movement is very smooth. The unit has undergone internal cleaning, the panel has been removed and the sponges washed with hot water, and the base of the knobs has been cleaned. All knobs are free of crackling or noise, and their movement has a good torque and is smooth. Headphone and microphone operations are good. This is a DJM-300 with all functions in good working order. We focused on using genuine parts and completed the maintenance by servicing the faders, rather than replacing them with new generic parts. The ALPS horizontal and vertical faders move very lightly and smoothly. #AlphaTheta #DJMixer #pioneerdj #IntegratedAmplifier #AnalogMixer
