BSS FCS-960 AUDIO 2ch 30-Band Graphic Equalizer

This is a graphic equalizer I received a long time ago.
It seems to have been used, but I currently don't have an environment to use it, so please consider it junk.

The knob cover for the gain is missing.
The knob has come off, but the parts are present.
There is distortion on the corner of the cover.

There are scratches and signs of use overall.

The power turns on.
Includes power cable.

Given the above condition, would anyone who can repair it be interested?

・1/3 octave, 30 bands.
・45mm fader stroke (gain range: ±10dB).
・Q can be switched between Wide/Narrow for each channel.
・High-pass filter with ON/OFF switch (variable 20Hz-250Hz).
・Bypass relay included for power failure.
・Employs MFB constant Q filter.
