    MC2105 Speaker thump

    Hi all I've got a well-loved but frequently-serviced MC2105. The current concern is that when it's powered on, I get some major speaker thump.

    McIntosh MR78 Replacement Bezel

    I am wondering if anyone has the demensions for the rectangular bezel that essentially frames the tunning dial area and meters on the glass faceplate of the MR78 tuner? It's held on by double sided tape. It can dry out and fall off. Mine is lost. It's the last cosmetic piece I need to restore my...

    Have you ever gone out in risky conditions to get your gear?

    I have to admit, I have. About 6 years ago I drove out into a storm in order to beat out the competition.
