Change Turbosound IP 2000 power supply from 110v to 220v


by dtolya


Hi guys!
I bought a Turbosound ip2000 speakers on the USA eBay and delivered them to Europe.
I was hoping that their power supply would have a 110v-220v voltage switch (American or European standard), as it is implemented in the speakers of many other manufacturers. But when I got my speakers, I was very upset not seeing the opportunity to change the voltage.
Is it possible to change the voltage in the power supply of these speakers without replacing the power supply?
I bought used speakers, so I understand that the manufacturer's warranty no longer applies to them, and I can safely redo the power supply.
Can someone help me?
