I am in need of a schematic for this speaker. I contacted Genesis but they are a new company and bought the Genesis rights thru bankruptcy, but they did not get any old info onsome speakers.
I have a hum that rises and falls with voulume, and when you wiggle the power cord, you turn the speaker on and off and get an electrical rush noise.
Obviously, need to correct this.
Any help, much appreciated
