Alex,
any guidance how to get this Pre amp working,
at couple of places its written bypass what is it for and what to do with balance.

I am Readying the BOM,
there is trim pot on Psu Pcb, How much to adjust it for what current.
And specification about brand of parts to be used or I can use as per availability.
