Question about Proton R5A Clock Radio
I simply cleaned my red switch by spraying it with tuner cleaner and the problem went away (it will return in a few years and cleaning it will correct it again). The switch can only be cleaned with the radio open. A can of tuner clean/lub with a small straw will be needed.

The electrolytic caps will fail due to electrolyte evaporating so replacing them will extend the life of the radio. the other parts like diodes, ic's, resisotors and transistors will be stressed out from voltage spikes and fail because the capacitors no longer can smooth out the ripple voltage common in audio amps since the audio level is always changing

I REPLACED ALL THE ELECTROLYTIC CAPACITORS IN MINE AND THE STATIC WENT AWAY UPON START UP, TURNING IT OFF AND EVEN PLUGGING IN THE ELECTRICAL OUTLET THE 1ST TIME. ELECTROLYTIC CAPACITORS HAVE ELECTROLYTE FLIUD INSIDE THEM THAT ACTS AS A CONDUCTOR OF ELECTRIC CURRENT. THE FLUID DRIED UP AFTER ABOUT 15 YEARS AND THE CAPACITOR NO LONGER FUNCTIONS. EXPECT TO REPLACE THESE EVERY 15-20 YEARS. I LOOK FOR 105*C CAPACITORS BECUASE THEY LAST LONGER DUE TO BEING SEALED BETTER AGAINST HEAT.
