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.
