Alesis SR-16 Stereo Drum Machine - no power supply

Here's a Good condition Alesis SR-16 Stereo Drum Machine. This has been tested and is fully functioning, although the pots are a tiny bit scratchy and the display didn't want to respond when we first powered it up, but every time since then it has been fine. Please note: this does NOT include a power supply. Unit is pretty clean with few dings, smudges and scratches. Selling as-is, as-described no returns.
