Krell 600c full balanced amplifier. Amplifier was used to drive a set of 801 Nautilus speakers. When a new room was built by the client his electrician failed to run a sufficient power circuit for the amp so he cannot use it in his new music studio. In his old house it ran great with the B&W speakers. I would prefer to sell this for local pickup since I would need to crate it to ship. If you are seriously interested for shipping I will build a crate and take it to a freight center. It is in nice condition. Available to demo locally in the Phila, Pa. suburbs. Item is way too heavy to return shipping so I marking it "as is", but will be happy to demo operation and test in any way required. Buyer pays shipping .
