For sale are a set of very nice McIntosh MC-501 500 Watt Solid-State Mono-Block power amplifiers. I rated them 8 out of 10 to be conservative. But both are in excellent physical condition. One owner, non-smoking household. Both amplifiers were cleaned and fully checked and tested by our in-house service technician. They include the original owner's manuals and power cords. They will be shipped in the original factory McIntosh shipping cartons for safe transport.
