I own a few Sammy machines and am familiar with the infamous "Sammy squeal", but it seems like my Speed Racer is abnormally loud when I'm not playing it. I don't have a volume control on this machine. It is easily my loudest machine. For those of you that own Speed Racer, is it also your loudest running machine? Is it possible that loud noise is supposed to simulate the driving noise of the car in the LCD? Any thoughts? Thanks!
