I'm very surprised the radio continued to work even while the capacitors you mentioned were destructing. Apparently, none of the defective capacitors were power supply filters, as you did not mention AC hum in the audio; however, if the filters were acting up this way they probably would have shorted and tripped a breaker, since they are in a position to short the power line directly to ground if defective.

I had replaced the supply filters prior to the bypass cap letting itself go. usually the first thing I do before plugging it in. That cap was a hard shelled plastic one too! (A white Sangamo cap), that came out /very/ hot. Surprised it didn't split and explode like the bumblebees do.
