This is for the 2226B but it may apply to others
How you rebuild a OEM Marantz switch for a 2226B and others. These are well built switches but often times have been carbonized with some arcing on the terminals. You use a pair of very thin bladed screwdrivers to carefully pry the metal tabs over the plastic ears and split the case.
Use a relay burnishing tool to clean the contacts along with DeOxit. People will say to use card board or very fine emery cloth but the tools are cheap and work well.
Get the sample of the non-conductive DeOxit lube and put a dab on each contact. The lube has DeOxit in it and will keep things clean and lubed. The Deoxit L260Np tube is a "sample" size but you use so little, it would last 4 or 5 switches. Make to get this one.. they offer some that are abrasive and some that are conductive.
Gently push the metal ears together a bit before pushing them over the plastic ears. As the case comes together, make sure the spring doesn’t get pinched in the case. I find that using the same thin screwdriver to hold the spring away from the case works well.
Pat yourself on the back for salvaging a piece of history and keeping your Marantz original.
