Just a hint I got. The "amplitude()" seems need to be in the exact format in your example.
I have tried amplitude (a +bi) does not work.

Just use the amplitude property of the source, which is a complex number
and can therefore set the phase:
(define gauss (make gaussian-src (frequency f) (fwidth df)))
(set! sources (list (make source (src gauss) (center 0))
(make source (src gauss) (center 0)
(amplitude (exp (* 0+1i phi))))))
