Its hard to imagine why this game is so hard to come by and why it has become so popular. It could be its scarcity, its theme, or its technology. Whatever the case, Voice of the Mummy, Milton Bradley, 1971 is one of the hottest board game collectibles since the resurgence of Dark Tower. I own a copy of this game for its sentimental reasons as I played it as a kid. I have also gone to great lengths to make mine a working copy. Despite my efforts to re-engineer the relatively simple technology requried to get the mummy voice working, it only does so about half of the time the reset lever is activated. When it does work, the voice is strange and otherworldly and worth the trouble. When it doesn't function correctly, it is the result of inconsistent speeds of the small motor running the turntable. The motor adjustment dial is incredibly sensitive with just a slight touch sending the mummies voice into helium mode, and yet another slight adjustment stopping the turntable altogether. Again, the age of the motor (going on 30+ years old now) probably has something to do with it. Among the people on ebay that I have spoken with, and including this page, more than 85% of the listed games available are nonfunctioning. The majority of these seem to me the result of old wiring, which is easy to replace. The others seem to be the result of a failed motor (nearly impossible to replace) and the final small bit the result of the membranous speaker. Unfortunately, unless you are very lucky, parts for these items are impossible to find. Most resort to parisitizing other incomplete copies to try and make one working copy. This I feel is your best bet. Nontheless, getting your copy working can be rewarding, I know from personal experience that after rewiring the game, and finally seeing the turntable move at the behest of a small 30 year old motor and thereafter hearing the mummies voice was a thrill. I wish you the best of luck in your endevours with this timeless game!
