Thanks to all who gave input. I did buy buy both pieces. I had checked ahead of time about the work. It was done by a shop that specializes in McIntosh gear, and they replaced the electrolytic power caps and the coupling caps, and brought both components up to specs. The C-11 also had a new glass face installed.
They are currently hooked up and sound fantastic together. Anxious to get them home. I appreciate the validation -- it did appear to be one hell of a deal, and less than 25 minutes away from me. No shipping worries! If I knew how to attach photos I would!
