Came with a house I bought, has been sitting for 10 years. I powered it up and fed it a signal through the AUX input. It sounds phenomenal! The input selector contacts are dirty and need cleaning, I had to fiddle with that knob a bit to get both speakers going at the same time. I would pissibly re cap it to prevent issues, but it takes an input and produces great sound. I note some dirt or stain on the faceplate, might clean off, might not. Slight bit of surface rust on the top but I don't see any moisture damage elsewhere and it works good. Due to it being vintage electronic item sale is as is. Good luck!
