These capacitors look awfully similiar to the small black capacitors on 
C107 and C108 (located in the VIC box) on the C64 KU-boards that will 
leak and damage the board. I think they were Matsushita, the logo 
looking a lot like the Mitsubishi one:

If you have capacitors with this logo on any old board, examine them 
thoroughly and if there is the slightest doubt replace them!
