[QUOTE="bmf85, post: 8521902, member: 670923"] Hey all! As stated I'm a newb, to the forum at least. And, just recently diving back into the realm of car stereos after a fairly lengthy hiatus. Anyway, I recently acquired an old school AudioPipe GD6001 for stupid cheap. When I got it, it was covered in dust and cob webs so I didn't even attempt to power it up. I took it home, blew it out with air and tried to power it up when I started to smell the lovely Fet burn. Upon opening it up I see 1 very burnt IRFP064 and corresponding resistor on the board. After further looking it appears what I believe to be the 4 drivers for those Fets have been replaced also and the ones currently installed are FMG32R. The smaller Fets seem to be in working order but are a mix of IRF9640 and IRF640 with some having been clearly replaced since manufacturing, some not. At the very end of the board on input side is a KIA7812A and a KIA7912PL On the output side there is one KIA7915P and one KIA7815A. Wondering if anyone has a schematic for the board or can just tell me what fets/drivers SHOULD be in there as it looks like someone did some replace only the 'bad' repairs. I plan to remove and replace all Fets, drivers and gate resistors as a project to learn more about fixing amps. Ive got a decent knowledge for electronics and how they function and am a proficient solderer. As soon as I get the board fully removed from case I will post photos. Thanks in advance! [/QUOTE]
