Negatively Biased
Beautiful pre amp I am very envious
I would clean all that flux residue off the boards with Isopropanol and a tooth brush
Only design flaw I see is lots of long wires ?. on the power supply why does the output run from one side of the case to the other and past the noisy rectifiers
In the pre amp I would have put all switches and pots at the back of the amp on extensions and kept all signal leads as short as possible
If you want to know the rail voltage why not just measure it
