Default Missing Caps;

Hi,

I'm refurbishing an old Sanyo DCA-200 amp and I noticed amp physically has two missing caps.

According to SM, there must be 0.1uf caps to ground (c73-c74). But looks like they never soldered to their positions.

Why manufacturer decided to not put them in their position? Is they unnecessary? What is their job in that position?

Any idea?

Rail decoupling. Apparently not terribly important in this particular amp.
