I agree with the AA person. What he is saying is very similar to what I had suggested. When I said that I felt the likelihood of a dc offset situation was minimal I was unaware of the hot transformer and hum symptoms, although I still feel that a wiring problem is more likely to be the cause.
I think it would be best to have a qualified person check out your ac. He should be able to very easily tell if there are any miswired or open connections, along the lines of what I and the AA person suggested, and he should be able to easily measure dc offset with suitable instrumentation.
