EDS3000.1FD-E0 class D full range amplifier

[mixalos spl]

good evening everyone...the above amplifier is stuck to clip led indicator....one output fet was short....it has 4...
anybody knows the component values?c4?c8?c3?c5?the output and power supply?h1?h6?

I'm not ignoring this but I have no definitive answers and anything I'd have to offer would require answering a lot of questions or testing. Someone will likely come along in a day or so with all of the definitive answers for you.

i simple try to be specific and with no extra words to get tired anybody....thats all....what i have done wrong?i dont understand...
appreciate any help if i missunderstood something....sorry for my bad english

 

[Perry Babin]

You haven't done anything wrong. It's the manufacturer that did wrong by remarking/defacing the ICs.

Someone will have experience with this or a similar amp and will be able to answer definitively. If I try to help, I will have to use a lot of different amp examples I have and ask a lot of questions to give answers that are less than definitive.

all right....i see...i think that its a chinese copy board and that explains a lot...???

This amp looks very similar to taraamps, probably a clone of one.

The output drivers, i think C5 in your picture (picture is blurry) is probably IR2010. The one next to it would be the same part.

Power supply FETs may be IRF1404.

Check your PM

The ones in the power supply are CSD18502KCS, but you can use almost everything if you choose the proper gate resistors value, irf3205, IRFB7434, also the IRFB7430, irf1404, irf1407 and so on....
The ones in the output section - the same....you can use irfb4227, irfb4115 and so on. Just consider the rail voltage and current requirements,
The driver ic's should be IRS20957S.

Thank you all very much....replace all output fets with new and the amp run loud and clear....thanks God no other issues....
everyone one thank you one more time....

Hello to everyone guys 👋🏼. I have one final amplifier from the brand bad habit. (SPL ELITE SE3000.1DF). I saw that the half of the transistors are writing H6 and the others H1 without any code. Does anyone know the code to replace it ? Please help me. Thank you so much.

sorry for the delay my friend.....usually H6 are irfb4115....and H1 must be csd18502kcs...if you need something more let me know...happy new year..!!!!!
