2. Swap Guide
Change all the OP-amps of the same types in the same slot. For example, if you
need to change DAC I/V (slot 1), you would need to change all the OP-amps of
the same types in all slot 1. If you need to change DAC buffer (slot 2), you need
to change the OP-amps of the same types in all slot 2.
