Hello,
I need help to identify the IC on the control board (DDaudio SS4a). The sound mosfets are 2pcs IRF640. Something tells me it will be IRS2092S ?? Does anyone happen to have a schematic or parts list from this device? The amplifier has been heated, a lot of SMD capacitors have burned out and I would like to find out their correct values 😡
Thank you for your help and your Time! 🙂

So you are looking for detailed pics of components? I just sold one of these and can probably have him take pics for you
It's odd that caps burn. They could easily survive the heat that the amp could generate.
Are the same caps damaged on all 4 boards? If not, you can get the value from the other boards.
For most driver ICs, you can use the pin numbers, the high and low-side output pins, the connections to the negative rail, the high-side filter cap connections.. to narrow down the possible ICs.
