Here are some replacement parts detailed below.
Electrolytic Capacitor List - Mainboard
Note that there is differences in the field with values of C4 and C36-38 which can be either 22uF or 47uF and occasionally 25V parts.
There seems to be no issue in these differing parts: C4 is the reset delay capacitor, C36-38 are used on the RGB lines into the Motorola MC1377P so are only relevent for composite video & RF output.
You can replace like-for-like or use the list below based off the bug-fixed schematics linked on the Internal PCB page.

C12 22uF 50V
C13 22uF 50V
C16 22uF 50V
