This is about 1999 vintage. It is rated at 130 watts/channel into 8 ohms; 170 watts/channel into 4 ohms; 360 watts in bridged mono mode. 10/10 sonic condition. Rated 8/10 cosmetically mostly due to age. This is a very clean sounding amp with a large open sound stage, lots of detail, and smooth presentation. I replaced this with a tube unit that really doesn't sound that much different. Price includes shipping to US. No foreign sales please.
