今天意大利人给我回信了,呵呵。
Dear Sir,
as you know the power transistors are very delicate components. To prevent short circuits to the outputs it's cautious to connect the cables of he speakers before to switch on the amplifier.
If you switch on the amplifier without any output connection you don't damage the amplifier, but when the amplifier is on, if you make a short circuit to the output, you can damage the power transistors .
Best regards.

哈哈,意大利人还是比英国人科学。
