My 1st tube amp: transformer buzz audible 15 feet?

I recently purchased my first tube integrated amplifier from a local shop. I continue to have problems with a buzz coming from the transformer, which I can easily hear while 15 feet away. Is this normal? Do I have a defective unit?

So far, the transformer cover has been tighten by the shop, and I plugged it into a variac to bring the voltage down from the 120-122 volts coming from my outlets.

After two weeks, I find the buzz unacceptable. Any ideas?

This is NOT normal. Return it and get a full refund.

This is not acceptable and is ridiculous for them to tell you anything otherwise.

There are plenty of other integrated tube amps that will NOT give any transformer hum.
