Question about Alpine MRP-M450 Car Audio Amplifier
SOMETIMES THE KNOBS THEMSELVES GET STRIPPED OUT AND THE CONTROL POTENTIOMETERS ARE FINE. YOU WILL HAVE TO INSPECT THIS TO DETERMINE WHICH IS AT FAULT. IF THEY ARE NOT STRIPPED, BUT CONTINUE TO TURN AROUND AND AROUND, THEN THE CONTROL POTENTIOMETERS ARE AT FAULT. LOOK NEAR THE CONTROLS ON THE PC BOARD AND YOU SHOULD SEE THE LOCATION NUMBERS PRINTED ON THE BOARD ITSELF. SEE BELOW FOR THE LOCATION AND PART NUMBERS:
VR101 18E39146S01 VOL,ROTARY 50K
VR102 18E39147S01 VOL,ROTARY 5K
VR103 18E39145S01 VOL,ROTARY 20K
YOU CAN OBTAIN THESE FROM PACIFIC COAST PARTS AT 800-421-5080, BUT YOU NEED TO HAVE SOMEONE QUALIFIED TO REPLACE THEM AS YOU WILL HAVE TO TOTALLY DISASSEMBLE THE AMPLIFIER AND ALSO HAVE GOOD SOLDERING SKILLS. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE....V
