GLI International Power Amplifier SA-2125 This is a great deal.....this amp is functional, however.......I'm selling at a very low price, as the dc offset is higher than it should be (on one set of terminals only) It needs to be adjusted. I'm the process of liquidating a bunch of audio gear.....I need it gone.....my loss is your gain!!!! Very desirable rack mountable amplifier in decent shape. Channels 2 (Stereo) RMS Power (Watts Per Channel) 250 x 2 @ 4 ohms Made by Spectro Acoustics in Washington State, better known for their equalizers. It was widely sold by a company called GLi, in Long Island City, NY that built pre-packaged sound systems for roller-rinks, and discos. Gli Built their own mixer/preamps, and speakers, but got their amps and e.q.'s from Spectro, and their turntables and reel to reel decks from Technics. These are really decent amps, sound nice, are more powerful than rated, and are VERY rugged.(they needed to be, for disco use!)
