	My friend from U.S.A With one BOSE ST-30 as shown in the figure, The machine uses 120 V AC voltage locally. After coming back, it forgot the power supply matching and directly inserted 220 V AC voltage. It was found that smoke was emitted and the plug was immediately pulled out. Now it has been checked that one 3.15A fuse was burnt out, and one used for voltage doubling filter was electrolytic exploded. The parameter is 470uF/250V, and no other abnormality was found with the naked eye. After replacing these two parts, it was powered on about 70 V AC voltage, No response (because there is no 220V to 110V power supply at hand, two 220V to 35V/100W transformers are used to connect two groups of 35V in series). Now please ask: 1; Is the power supply voltage too low? 2; Are there any parts damaged?

	Just now, two transformers were used to form a 126V/100W output. After power on, I was surprised to find that the power could be turned on. After power on, the voltage dropped to 112V, and the power could be used normally. Under low volume, the transformer ran for an hour without heating.
