Anyone have a copy of this service manual? Pacparts doesn't sell them. :/ (Likely due to the recall.)
I have a decommissioned (recalled) unit that I'd like to be able pull some parts from for testing another amp. The parts list from the service manual would make identifying parts much easier.

That's the first recall I've ever seen for an amp.
The problem may be easy to resolve by installing wire in the vias.
I don't have anything on the amp.
Are the parts defaced?

From what I have seen, the recall procedure was to make the amplifier permanently inoperable. Holes put in the boards and the fuse terminal got half the contacts removed. These decisions were likely driven by potential liability.
At some point I'll be talking to the guys at a local dealer to see if they'll let me see the dealer-only documentation. If you read the publicly available notice from Alpine (which it sounds like you did) you'll have seen that documentation mentioned at the bottom.
I technically could repair this amp but I have absolutely no desire to. Trying to rebuild the broken traces isn't worth my time.
None of the parts are defaced but some of the smallest parts are not marked. Couple that with my inexperience in identifying SMD parts results in my hesitance to experiment.
At the moment I'm specifically interested in identifying these diodes marked "UF 02"

I didn't realize that yours had been damaged. I thought that is was simply slated for recall and you were trying to rectify the problems.
The resistor connected to the diode looks blown. Is the diode shorted?
Is this from the PDR or from the amp that you're trying to repair?
Marking smd
The only thing I see is a Zener.

My mistake, I should have been more clear.
Yes, my PDR is a unit that was recalled. It exists for nothing more than donating parts while I troubleshoot other amplifiers.
The picture is of the PDR-M65 parts unit. The resistor just has some flux residue on it from the factory and measures in at exactly 22 ohms, not that it matters since it's on the junk board.
Sorry about the poor quality picture, it was just to give you a visual on the diode I'd like to identify.
The amp I am working on is an MRV-M500 with a bad KDS160 (data sheet) in the output section (D3601) as well as a few other other parts.

I'm confused. The KDS160 is marked exactly the same as the photo. Why is there a question about it being the same?
It's not so much confusion as it is that I want to be absolutely sure it's the same part before I swap it in for testing. Being able to compare part numbers would set my mind at ease hence my request for the service manual or parts list.
I've only been repairing amps for a couple of months and am weary of making a bone-headed mistake. Perhaps I'm being overly cautious.
