Kenwood mini-stereo model:KR-595,year:Jan 1996,unit shuts off when power button is pressed,here is history:



Aug 7,2004: Replaced right channel: Q18=2SD2222=NPN=shorted Q20=2SB1470=PNP=shorted F13=5 amp power supply fuse=open



Feb 18,2005: Replaced: Q20=2SB1470=PNP (again) (different supplier)=base to emitter open



July 19,2005: Replaced: Q20=2SB1470=PNP (again another different supplier)=base to emitter open



And now Aug 16,2006: Q20=2SB1470=PNP=base to emitter open



Before I replace Q20 again WHY IS IT FAILING SO MUCH?.



Thanks in advance.
