Quoted from Chosen_S:The diodes are on the pcb
On my machine, there is a sticker on the side paper showing the fuse layout. The sticker indicates 4 amp slow blow. I checked my F3 and F1 fuses. They are both 4 amp slow blow fuses. The original side paper shows that they were 2 amp slow blow.
I have an early production machine with the clear ramps.
Maybe this helps some...
