... drive low impedance loads directly, valve audio amplifiers must employ output transformers to step down the impedance to match the loudspeakers ... Output transformers are not perfect devices and will always introduce some odd harmonic distortion and amplitude variation with frequency to the output signal ... In addition, transformers introduce frequency-dependent phase shifts which limit the overall negative feedback which can be used, to keep within the Nyquist stability ...

    And gave her mother forty whacks;
    When she saw what she had done,
