kleinteich2 Posted May 5, 2012 Report Share Posted May 5, 2012 what is the big round things on the left in the middle of the pcb? and where can i get one? Quote Link to comment Share on other sites More sharing options...
timwebb Posted May 5, 2012 Report Share Posted May 5, 2012 the two red one are the transformers and the dark one is the inductor. u cant buy them u have to have them rewounded. do u have an amp that has bad transformers? Quote Link to comment Share on other sites More sharing options...
kleinteich2 Posted May 5, 2012 Author Report Share Posted May 5, 2012 Yes. AP15001D can't I steal them from another and replace? Quote Link to comment Share on other sites More sharing options...
Lbox88 Posted May 5, 2012 Report Share Posted May 5, 2012 Yes. AP15001D can't I steal them from another and replace? If it is the same amp sure, otherwise no. Unless you want to blow something else up. The fact that you didn't even know what they are tells me you have no electrical background and I would suggest you send it in to be repaired instead of possibly smoking it again.

Guest Posted May 5, 2012 Report Share Posted May 5, 2012 that amp isn't worth it to get rebuilt. and going by your questions, you'll probably just fuck it up worse if you try to fix it Quote Link to comment Share on other sites More sharing options...
kleinteich2 Posted May 5, 2012 Author Report Share Posted May 5, 2012 Lmfao.. I know Alot about electrical repair. I've just been wonderg why the audiopipie schematic calls it a power inductor.. the schematic I have is straight from the factory in China. So it might just be the translation. Idk. But thanks for the input guys. This is not my first repair.. lol Quote Link to comment Share on other sites More sharing options...
Lbox88 Posted May 5, 2012 Report Share Posted May 5, 2012 (edited) Oh ok, just making sure since the way you worded it just sounded like you were completely new to this. I'm kind of on the fence now though. We all know how chinese translations can go lol. But when I was in college we built a class D amp from scratch including wrapping our own iron core inductors and wiring the transformer up. If it's a direct swap from one ap1500 to another then do it since they aren't worth the cost of having them repaired but a little bit of your free time might get you a working amp. Just be careful not to burn the PCB and use adequate thermal paste when remounting the FETs. Good luck.
