How do you clean out the switches on the 52? I tried just spraying through the sliders but it didn't seem to penetrate it. BTW, if people haven't heard one of these little units, they sound way better one would think for the size.
what i use is USTANOL from Balistol, slightly sprayed into the slider, but you'll have to open the unit and undo plastic- covers to reach properly. That's my best experiance, and I'm a trained radio- and tv- mechanic since 1986 (...works great on magnetic memories of juke-boxes as well )
