Offered here is a beautiful and clean 6 transistor shirt pocket radio from RCA. This radio is cosmetically excellent and so is the black leather carrying case. Inside the radio is clean and when tested with 4 volts of power, it worked loud and clear. But you will need to obtain a round 4 volt to enjoy it. Small at only 3.5 high, 2.5″ wide and 1.25″ deep. All original.
