Help needed: Convert US-NTSC PSU to PAL (110V to 240V)

[jacobsson]

Hello.
I have 5x 110V NTSC power supplies on my hands. I love to modify them to accept a wider range of voltage (basically make them region free): 100V to 240V.

My first understanding is to swap the 200V capacitor on the AC side to a 400V, but which value?

What components needs to be changed?

Wow, that was fast. I really appreciate this!
Does this mean it can now accept both 110V and 220V?

I think just 220v after,test if you want ^^

It seems like my PSUs are of another design (Mitsumi)
There are no JP1 nor R13 in series with the capacitor.

Oh, I understand now. Your link is for Japanese PSU only.
My power supplies are US NTSC, not JP NTSC.

Ho yeah not the same PSU..I don't know... I had just this PSU any times,maybe Japanese PSU
