I would recommend a new rectifier board and rectifier connectors. And yes your driver board has been re-capped. Finally all the black tape on the connector is concerning. Why is it there? The tape on the MPU connector is most concerning to me (first picture upper right corner).

Edit:
Just to be clear, some of the fuses look original and i've found issues with old fuses. Also, it's very common for the old rectifier boards to have issues. I believe the design was to use the metal backing plate as a heat sink for the 3 rectifiers. And overtime the conductive material dries up and stop working, thus causing overheating issues.
