I HAVE A SONY XM-444 CAR AMP WITH SOME BADLY FRIED COMPONENTS AND I NEED TO IDENTIFY SURFACE MOUNT RESISTORS R927 AND R928.CAN ANYBODY HELP?THANK YOU.
They are both 47 ohm, gate feed resistors to the two MOSFET's in the PSU. Presumably the MOSFET's were blown?, and you've replaced them?.
Thanks for that.i have ordered some irfz44n fets to try as the origional fkv550t fets are far to expensive.
I don't know how experienced you are but if the fkv550t are fully encapsulated, you'll need to use an insulating washer and insulator to electrically isolate the IRFZ44 from the heatsink. If you need fully encapsulated replacements, IRFIZ44s are fully insulated.
