A generalized non-Hermitian oscillator Hamiltonian is proposed that consists of additional linear terms which break PT -symmetry explicitly. The model is put into an equivalent Hermitian form by means of a similarity transformation and the criterion of N -fold supersymmetry with a position-dependent mass is shown to reside in it.
