Electronics: Preamp Number 1 (old project)

Board purchased off Ebay

The board is supposed to be an MBL 6010 clone, but it isn't correct.

This didn't matter to me, as I just wanted a quad single OPAMP board that I could modify.

The input stage is now a buffer, and the second stage has reduced gain.

The volume control sits between the two stages.

I also have some RMAA test results somewhere as well.
