ALPINE MRV-F401 diode identification.

[rhempz01]

So I received an Alpine for. I believe no audio. I did not attempt to power it up as I noticed a burnt diode in the center of the amplifier right away. What is this connected to and a part number would be helpful. D512

What's the diode connected to in the circuit?

If you can see the silkscreen, install another diode like a 1N4148 unless the designation indicates that it's a Zener.

I have the same problem, need to ID the D512 and buy a replacement.

Yeah, I would like to know the D512 too! Mine is burnt. Thanks!
