Can someone explain the optional parts for me.

I have the SC25 opamp with the A-12. What do I need to put in of the optional parts and what do I not need to put in. I am a little confused on this subject. Please Help! Thanks!

R22

R19, R20

C2, C7, R20, R22 - not included, don't worry about them unless you're using an IC op-amp, a Lundahl input transformer, or the DC servo

R19, L1, L2 - install a 0 ohm jumper, included

For this config I noticed that C18 and C19 (ceramics around the IC opamp) are also not needed.

Perhaps they could be "optional" in the BOM?
