I have heard advice to ground the negative pin - never did it.
 
Mine is on the floor -- under the desk -- and I leave it on all the  time. 
After three years, it is still happy.
 
If you power on your radio by leaving it's switch "on" and turning your  
power supply on and off, you may be getting a surge the radio is not  liking.  Try 
turning on the power supply first, then the radio.
