Up for sale here is this brand new 6-pin pushbutton switch.  This will work great to replace pretty much all of the old 6-pin pushbutton switches in the 1970s Marantz receivers.  It will replace the loudness, FM muting, low filter, hi filter, hi blend, tape monitor 1/2, and multipath switches in the Marantz 2275.  It is the same dimensions as the old switches and will fit nicely into the board and into the metal frame.  Cleaning your old switches is a waste of time if you can just replace them.  This is a normal pushbutton switch--you push it once, it goes in and stays in, you push it again and it pops out.  To install this, just bend the tabs in the old metal mount, remove the old switch, put in the new switch, bend the tabs to hold it in place, then solder all the wires.  To use this as a multipath switch you'll need to remove the little locking tab on the switch, which is fairly simple.  I have other pushbutton switches listed, just take a look.

Just FYI, the original Multipath switch is NOT supposed to stay in, so it will just pop out when you let go.  That is normal.
