Not if it works for you. Is your system using NSTs or similar
transformers or a pole transformer? It matters when it comes to
performance differences and also the probability of you transformer
having a long life. For the small system in the book which is using a
NST, a rather vulnerable transformer is being exposed to high
amplitude ringing it could matter a great deal.
