The balance out of the pre if has a zero central it is connected to pin 1
Thi is balanced ground
And with the output line trafo is normal
Just to check

In a balance connection, pin one doesn't have anything to do with the signal. It is chassis ground for shielding purposes.

In a differential circuit, the center point between the two signal lines is grounded so between ground and either signal line you have identical but out of phase signal.

Those are two different things, related but different. People tend to conflate the two.

  As wrote If the pre has a trafo there are two possibility.
  And also if the circuit is w/o trafo ; you have the reference of the ground of circuit
  In every case the use of 3575 Sowter, for example , is a fine solution
