Project: Preamp Number 1

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.
As soon as I find the schematic I'll post it!
I also have some RMAA test results somewhere as well.
