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.
