This is a solid state made by Audio Research. Think it’s from the 90’s sometime. Here is what I got off another site about the amp: It’s conservatively rated at 110 Watts per channel into 8 Ohms and 200 Watts per channel into 4 Ohms. It packs a hell of a punch even when pushed a bit hard. No signs of running out of power. Think it retailed for around $3000, not sure.
