If no one can help, post a photo of the inside of the amp and I'll see if I have information on a similar amp.

The OVN1-4000 seems to be very similar. On the OVN1-4000 and the OVN1-5500, there is no component installed in that location.

The OVN1 amps have a serious design flaw that causes the legs of the FETs to break. If any of the legs were weak, they're likely to break soon. You need to install a support on the top and bottom of the board to sandwich it between the heatsink and the bottom cover to prevent the board from flexing.

You are correct 4 fets had broken legs and started arking when i power it up.After resoldering them the amp power up fine and is playing good audion.I think i will use some silcone to keep the board in place. Thanks

You need to use something to support the board in the middle and that's not going to be difficult to remove if you have to disassemble the amp later.
