240V into a 110V US PS2

After succesfully installing an M2 into a US version1 and feeling pretty pleased I then managed to make my most stupid and anoying mistake since starting to mod PS2's.

I went to give the PS2 once final test before the owner picked it up, and clean forgot about the step down transformer... something fried.

I've checked every fuse on the PS2's mainboard I could see. All were fine.

I then checked the fuses on the PS2, the glass fuse was fine but the white fuse had blown. I replaced this but still the PS2 has no life, I'm hoping its just the PSU blown as the red standby light doesn't even illuminate.

I'm just wondering if anyone else there has a US PS2 in the UK and has managed to make the same mistake as me ? If so did replacing the PSU fix the problem ?

Tee shirt! The Zener diodes have blown on the power supply.
