This is my restored analog solid state Optimus (Radio Shack) MPA-250 PA Stereo Amp. Actually made by Pyle Pro Audio for Radio Shack and re-branded. This is an awesome amp. Super clean, retrofitted VU Meters with blue LEDs. All Joint re-soldered, pots cleaned and fresh heat sink grease. These amps can pound for hours without breaking a sweat.
The sticker on top of the amp it just a sticker and this amp has no relation to Alesis at all. :)

Here is a few links to more info: The Pyle Audio link is only for a visual reference.
