The Sansui p-130 transformer has a bias out of 350ac vs the orig 340ac, and the BYV26E-TR diodes have forward voltage of 2.5v vs the 40ish of the 5u4gb, the SAMs shows the rectified voltage was 390v originally, this will jump up quite a bit

Why not use the 300 volt taps on the hv (350V) secondary? Might work about right with the reduced ss diode forward drop.

did not think about it that way, it my work with the original resistor setup.
