It's retail price in 1984 was 450. This is a vintage audiophile quality unit. It won't produce sound and only the power and dad indicator lights light up Denon pma 757 pre main aka integrated amplifier, serial no.
But at any rate, clearly it is in need of service and repair. The speaker jack is the worst of it though, otherwise there's a little chip above the speaker selectors on the face, and a couple of white marks on the right side of the unit, so it's in pretty good shape cosmetically.
In decent shape cosmetically, but one of the speaker jacks is bent and a bit of the plastic has broken off around the edge of it, which is apparent when it's unscrewed all the way but it still screws in okay and you can't really tell when it is screwed in completely. See the pics for more detail.
