Hello, I am working on restoring a Classic II. It was missing a ram chip when it was obtaned. On start up it had only the diaginal bars but would play the boot chime. I have replaced the ram, and now i get a diffrent lined image but only a strange buzzing noise insted of the boot chime. I am planing on replaceing the caps, i have not ordered them yet. In the mean time dose anyone have any other ideas i could try? I have attached a picute of the current lines below.
