In our latest edition of I Don't Know Stuff we are diving into the Marantz 2240 and giving it a good clean up with some Deoxit, brushes, and canned air. This is what you do if you hear scratchiness on your knobs on old gear. This works for all of them but I'm particular to the Marantz 22s so let's dive in. If you dig what I'm doing and you want to join the community we are building search for THE VINYL HEARD on Facebook and ask to join today!
