I don't have the component list, but all required components are printed on the PCB. Perhaps, u may have reference to www.shine7.com.

This crazy guy nearly finish BPA300 board

.

Actually, I am often surfacing on some Chinese diy web site where u may find a lot of cheap stuff such as LM3886 chip, pcd etc. However, some of them might be fake. If u really want to buy something from them, u have to pay extremely carefull.

I may give u his email, but I don't know whether he can read English. U may PM me

This works without the additional op-amp components in the BPA200 module, listed on subsequent pages of the same PDF?

That might give me enough power to satisfy my basstooth.
