Sorry to hear of your loss.

Perhaps some time on the McIntosh site can yield some answers. McIntosh, like many manufacturers, have an extensive online library of literature (brochues, manuals, etc.).

Also, it might be advantageous to also order "The Complete Guide to High End Audio" by Robert Harley.

Good luck and... welcome to the world of hi-fi audio.
