RF prime R500x1D

I think these are the PS FETs.
Anyone has a source or sub for them?

I found the Alpha & Omega at Digikey link below:

AOT460 Alpha & Omega Semiconductor Inc. | Discrete Semiconductor Products | DigiKey

This is a link at Mouser for replacement parts. I'm not familiar with them, we use the AOT460 at Kicker for several amps. This is the mosfets for the power supply btw.The amp looks very similar to a number of Kicker amps if you post what symptoms you have I may be able to help you further.

I thought the bottom number was the part number.The power supply fail in this amp.

Is the PWM a TL494 and is there an 18021 8 pin IC driver for the PS mosfets by any chance?

yes
I place order for IC and FETs already.
