Right, measuring R2, I was getting different results on the two PSUs. On the faulty PSU I was getting exactly 100K and on the working PSU I was getting much higher readings. The higher reading most likely due to the two big bad ass caps that connected to one leg of the resistor. So, I decided to pull the caps to see what was happening:
So, I took the two caps out of my good PSU and put them into the faulty PSU, and it's all back up and running again. The ripple has gone, and I now have a nice clean 5v.
I now need to go source a couple of those big capacitors. I definitely don't have any of those lying around.
Thanks for the pointers!
