Wurlitzer reed organ amp and speaker

This is a Wurlitzer electrostatic reed organ it has a box full of reeds that are picked up electrostaticly. Basically it creates a bunch of fluctuating capacitors that change the voltage so when you press a key and complete the circuit it makes noise. It stopped working so I just started using it as a amp instead of using it to practice organ. Several pieces of sheet music fell onto it while recording causing it to become distorted
