  1. I received a message from Dawn 5000 about an hour ago trying to scam me to contact a friend of his or hers to purchase a McIntosh MC225. Told him I would only deal thru the forum here. But that was not good for him.

  2. Original owner, excellent cosmetic and working order. Comes complete with Microphone,Tripod-Boom,Cables and remote control. I have the box for the unit but missing is the smaller boxes for the accessories. Asking $3500.00 

    May consider trades. Always interested in Altec components and possibly a nice SET amp.
