In the area around the main filter caps and the area around C187 in the amp section there were a number of corroded jumpers. In all I replaced 16 jumpers. Everything in these areas was removed cleaned and checked for corrosion. In the end I only had to replace 3 resistors and 2 zener diodes. More on them later. Again, I used a 1mm drill bit to hand clean the remaining glue from the pcb holes before installing/re-installing a component.
There are surprisingly few caps in the PSU section, only 5 including the main filter caps.

Zeners C125 & 126. One had been replaced and the other had corrosion. Here is where my inexperience with zeners makes for questions. I found a data sheet for MTZ zeners and for the MTZ-16C it showed 15.69 - 16.51v. I'm used to finding the center of tolerance and using that as nominal, which in this case works out to 16.1v. Being unsure if that was the correct thing to do I ordered both from Mouser.

And in the end I used the 16v from Microsemi. I have no idea if I did the right thing, but on the other hand the amp works beautifully, so, Huh.
Also, next to those zeners are some big 2w MOX resistors. R263 & 264 (2.7kohm) and R262 (1.8kohm). They were all corroded so I replaced them with 2.7k KOA Speer MOX 2w MO2CT631R272J and 1.8k KOA Speer MOX 2w MOS3CT52R182J.
