THE DIODES CAN BE REPLACED WITH 1N1191A, THEY ARE "REVERSE" POLARITY, AND CAN BE SCREWED DIRECTLY TO THE CHASSIS. I HAVE USED THEM MANY TIME WITH GREAT LUCK... AND THEY HANDLE LOTS MORE CURRENT THAN THE FACTORY ONES DO.

The diodes CR1 and CR2 are compression-fitted style rectifier diodes that are pressed into a rectangle stock of aluminum, and the aluminum is then secured to the chassis via two screws. The diodes have one solder lug terminal. The service manual only lists the Motorola part #; no specs or industry-standard part # is given. Same on the caps. Only spec given is 27,000 uf @ 20wvdc. I did a quick search of Mouser and DigiKey, and was unable to find any chassis-mount style caps. Anyone find something suitable that can be re-secured to the ps's chassis via new rivets or screws? I know I can just solder in any cap that meets electrical specs, but I would like the caps to be secure and not have the ps become a fire hazard waiting to happen! The power supply was still sitting in my truck last night. When I get a break today I will take it apart further and see if I can find a part # stamped on the diodes and caps that might indicate what the real part # is. While I was at the repeater site yesterday I thought I saw a 1Nxxxx stamped on the diodes. I would have thought that there would have been someone here on the list that has repaired one of these supplies before, so that is why I asked.
