Mains transformer blew up amplifier, incorrect description in wiring instructions?
You are correct in what you have determined, the connections should be wired as you have described and not per the documentation. The only exception would be to use brown for live and blue for neutral to conform with wiring standards.

The transformer you are using is different from the one they have picture/documented, in that the black and blue wires have swapped purposes.

As a word of caution to others finding this question: the manual does state to be careful of different colour schemes.



The net result is you will have connected mains directly to the amplifier, most likely destroying some or all of the circuit.
