No, no holes and no sign of any missing components on the board at all.
I think the reason for this is mine is an older model with the two breakers on the front (no fuses) and the schematics are for the later PC 702 with the fuse. I have the later A-4 too and just pulled the chassis and confirm the schematics match it identically.
I say later but according to the tranny and pot numbers its only later by a couple months
