V100 circuit confusing

Hi there i am assembling V100 as a part of my school project but looking at the circuit diagram in the manual i am bit confused coz there is two circuits. It would be really appreciable if anyone could just explain what both the circuit means. Thanks in advance!!!

You are probably referring to the VM100 amplifer module.
If you are assembling it as a kit, you’re talking about the K8060.

Sorry, circuit descriptions are unavailable.
Maybe someone on the forum can help?
