I guess I'm very lucky. The mainboard of my new Plus looks phenomenal. Just a bit of dust. It has 4 MB installed. The caps on the mainboard are of normal axial type:

5x 33uF, 16 V

1x 1uF, 50 V

All are ca. 13 mm long (just the body) and their solder joints are ca. 20 mm apart.

The caps look very good, no goo. Is a recap advisable anyway?
