Factory Authorized McIntosh tech, and the service manuals have ZERO disassembly instructions. In fact I broke a few faceplates at first.
Good news, McIntosh has been remaking new glass faceplates for their vintage units for years, and they usually run under $200, so if you ever want to buy a new one, you have that resource.
Bad news: the new plates come GLASS ONLY, so you have to reuse the old plexiglas light-pipe and using the thinnest double stick tape is paramount. Also if there is ANY warpage in the glass plate framework, guaranteed the new plate will shatter upon tightening the frame during installation.
Best to overlook the bubbles and wait until you are ready to invest in a new plate, otherwise you will make it worse trying to "rehab" the glass.
My two nickles.
