RE: " A toroid transformer would be worse."

Unless special measures are taken, the frequency response of a toroid PT is generally much better than an EI cored transformer. The extended HF response couples more HF junk on the primary to the secondary. The HF performance of many toroid PTs is extended enough that they have been successfully repurposed as PP tube OPTs.
