External PSU shuts down the breaker

Hi! I have a Gold Note PH10 phono and just received the PSU 10. After I turn on the PSU, it shuts down the breaker in the house. I have tried to plug in without connecting the phono, same results. It was all right when I tried in a HIFI shop, and worked well, even connecting to the phono. I would be suspicious, but every single component is working good (with higher load also), except the PSU.
What can it be?

Perhaps it is tripping a ground fault interrupter (GFI) circuit protector in your home while the problem is not a dead short that would trip the circuit breaker at the stereo shop if it did not have GFI protection.  In any case, I would not want something that is tripping breakers and raising safety concerns even if it "works."

This unit has a low voltage linear power supply for a solid state phono preamp/equalizer.  It should not have a massive bank of capacitors that would draw enough current to trip any kind of breaker.  I would not fool around with something that might be faulty--not just because of safety concerns, but, also because I would not want to fry other downstream components.
