The Debut III if I am not mistaken is a non-US model More than just the power supply would need to be changed. The pulley system, the motor AND the power supply need to be swapped out.The Debut III has been a US model for at least 9 years, and is still a US-distributed model. It's most likely that his current version is a US-spec model. It just isn't very good, and it may have been an assembly line lemon.
However, I don't consider even the current version of the Debut III as good a value as the Debut Carbon DC, which, for $75 more gives you:
- Carbon fiber tonearm
- Ortofon 2m Red cartridge instead of tossaway OM5e
- DC power supply for improved speed accuracy
