Hi everyone, I want to change a Pioneer LX305 from 110V to 220V The transformer is a NPT-1672D. As I understand it I can swap that with a NPT-1672M for 220V. That's easy. My question is the board (I believe it's the SMPS) numbered BCPS-2572. Does that board need to be changed? Or can it work with both 110V and 220V? TIA  |

There is nothing about this difference in the service manual?

I converted a US Pioneer VSX-53 to UK voltage using a main transformer from a scrap SC-2022 and it worked. The primary/standby switch mode supply is designed to be worldwide voltage range and just has a different main fuse fitted. I think it was a 12A for US and 6.3A for UK but that was the only difference I found.

There is nothing about this difference in the service manual? I don't have the service manual for this model (LX305). I have seen other Onkyo service manuals, and assuming they are similar (they look similar), but I don't have the skills to look at other models (like Onkyo NR676) to know if the board needs to be changed or not. I have asked something similar on this board about the power conversion for the Onkyo NR676, and someone mentioned needing to change a capacitor. However I never got a d definitive answer. |

Hi randomaudioguy Did you manage to do the conversion? I am interested in this because I want to do the conversion on a Pioneer LX305 too. |
