His implication being is that while it would work, e.g. no hum, etc, it just would not perform as it was originally intended.
Not sure where he's coming from here, the components after the power supply don't get 110V anyway (unless that is the specified HT). If the PSU is properly specified for the mains supply then the output voltages and currents will be the same. In practice we do see wrongly specified transformers which will effect the voltages to some extent. I wonder if the different A.C. frequency will have an effect on the performance of filtering components (60Hz U.S.A. 50Hz Europe)?
