Does the power pack state it accepts 220-240 volt current?

The unit doesn't matter, it takes converted DC current so it's the power supply you need to check.

This replacement power supply clearly states 100-240V so would work fine here. You can either get an adapter plug or cut the cable and wire in a new one: https://www.amazon.com/T-Power-Compatible-Amplifier-Replacement-Switching/dp/B01L0P9KVS
