Forgetabout simulations, how much hum pickup do you actually get in real life?

I cannot believe a simulation can give you ANY hint of hum transference from power TX to OPT. What spice maker has ever modeled audio transformers with this in mind?

37mV would be a HUGE amount if that was appearing at the speaker terminals. A target of 1-2mV is more like a top amp.
