Pioneer DJM700-S [Junk]

This is a used Pioneer DJM-700 mixer in silver (junk item).
It powers on, but the knobs are sticky (one is cracked) and the headphone jack only outputs sound from one ear. The master volume sometimes becomes low on either the right or left channel.
It has been sent to Pioneer for repair twice in the past. [Repair of the effector and repair for the master output not working.]
It was used continuously for about 10 years in a commercial establishment (restaurant), so there are many minor scratches.
Due to its poor condition, it is being sold as a junk item. For those who can repair it or use it for parts. Please purchase only if you understand this.

No box or manual.
Includes only the main unit and power cable.
