Currently, the soundbox does not allow for proper transfer of the sound. Inside the soundbox is rubber that helps isolate movement. There is a coil with very fine wire that gets tied into it. The coil floats on rubber bushings and it must be as free as possible so as to not distort sound. The needle goes in and vibrates up. But the rubber has stiffened over time and currently does not allow for sound to travel without distortion . The coil needs to be pulled out and gingerly unsoldered from the soundbox to change the rubber pieces. The potentiometer also has an oxidized crimped connection that no longer works.
