[Jukebox-list] RE: W2800 really frustrating lift arm problem

[Wesley Dean]

    Jens, you misjudged me. At that time I worked for the Wurlitzer for Georgia and South Carolina and the firm was very aggressive. Do you doubt that we sold hundreds? If you had read the original message closely, you would have noticed that he stated that it would jerk without the carousel installed. This is very indicative of my description of the problem.Wes
