What have I got today?
Old school boombox. Yes... another one. The radio works and the cassette player acts funny. Sticky gears. Pop the thing open, spray in some WD 40, close it up. Leave it run on fast forward all night. Tomorrow, leave it on rewind all day. That dries up the excess lubricant and so all the gears will turn normally. Good to go. Some idiosyncrasy: The cassette can be active while the radio is playing. So, right now, my cell phone is connected to a transmitter and the radio is blasting out Swing Republic.
If you want to pick THAT type out of a crowd, just look for the festering scabs on their elbows.
