revoracing247 Posted September 18, 2012 Report Posted September 18, 2012 hey so i have this Memphis PR1.1000 and the window in my truck apparently wasn't sealed all the way and after a night of rain...you guessed it. i didn't know it and the next thing my car was filled with smoke . anyways i pulled my amp out and pulled the cover off and the heat sink and found that it looks like 4 of the transistors had shorted and the 2 bigger ones had completely and cracked apart. here's some pics of the damage and removing the bad ones. and the bad transistors: anyways, so i just ordered some new ones and hopefully i'll have them here in the next couple days but my question is: when transistors short, is there usually anything else that goes bad on the amp? i've scoured the board over and over and haven't found any burned resistors or popped caps. if anyone knows anything about fixing amps, any input is greatly appreciated! ~ If it was easy, everybody would be doing it ~
revoracing247 Posted September 18, 2012 Author Report Posted September 18, 2012 if anyone has even just replaced some fried transistors and the amp worked like new again that'd be nice to know ~ If it was easy, everybody would be doing it ~
8ight Posted September 18, 2012 Report Posted September 18, 2012 Sorry to ask but can I get a gut shot? I can't find one anywhere for that amp, and I love me some Memphis. I'm gonna hate
revoracing247 Posted September 18, 2012 Author Report Posted September 18, 2012 Sorry to ask but can I get a gut shot? I can't find one anywhere for that amp, and I love me some Memphis. sure thing! i'll get one when i get back from classes today ~ If it was easy, everybody would be doing it ~
revoracing247 Posted September 18, 2012 Author Report Posted September 18, 2012 sorry it took so long, stuff always seems to come up anyways here's a couple pics im gonna do a whole post in amp guts with all the photos ~ If it was easy, everybody would be doing it ~
finkster Posted September 18, 2012 Report Posted September 18, 2012 I would send the amp in to Db-r to at least get checked out. He can tell you what you have to replace. Something could be very wrong and you not know it.... DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living

Something could be very wrong and you not know it.... i've seen Dd-r mentioned on the forum before but don't know much about them or anything. the thing is idk how much i wanna spend to bring this one from the dead. im just kind of looking for something to push this JL 12 i have so i can build a t-line for it and what not, just something to have fun with and keep me busy till i have the money for a bc2000 figured $10 in transistors is worth the gamble. ~ If it was easy, everybody would be doing it ~
revoracing247 Posted September 19, 2012 Author Report Posted September 19, 2012 im thinking irfp064n lol yup, should be on their way: 2 IRFP064N and 2 IRF9640 ~ If it was easy, everybody would be doing it ~
Guest Posted September 19, 2012 Report Posted September 19, 2012 i heard that you should replace all the transistors, not just the ones that are blown. parts from different lot numbers could have slight variances in them, which can possibly make the new parts work harder (or the older parts work harder).
