You have a few options if your AR II board has already gone dead. You can technically replace it with any small amplifier that will run off the available power in your cabinet, this will require a little custom wiring though, and it will slightly devalue your game. The better solution is to get an AR repair kit, and fix your own board. It is a straightforward thing, and anyone who can use a soldering iron can do it. Repair kits are usually under $15, and replacement AR boards are usually around $30 or so (prices current as of September 2002). It is easy and cheap to fix the missing sound that many Atari games are afflicted with, so there is no excuse for a silent Tempest machine.
