This is a great amp. It's in my vacation home in a ski area in Alaska. Lousy snow recently and i don't get up there much so I've decided to sell it. Bought it NEW from Spearit Sound in April of 2015. Light use. No scratches or blemishes that I can see. This is not a refurbished unit. This is a hybrid unit, tube in, solid state out. 400 WPC into 4 ohms. I rate it 9/10 only because it has been used in my system. Here are the specs from the CJ website:
