Be sure the NEG sides of 59A and 57 are not to ground, but to the HV center-tap. This is also the NEG side of cap 59. The POS side of 59 goes to ground which filters the negative grid bias for the output tubes.
Note that in the schematic, cap 59 is drawn with the incorrect polarity and the POS terminal should go to ground.
