Quite a few SMPS designs use a 330VDC bus regardless of whether they're made for 120 or 240V. The difference is that 120V models wire the rectifier and capacitors as a doubler while 240V models will full wave rectify the input. I have converted a couple of 120V devices to 240V by rewiring the input section and adding a second capacitor, the reverse is easily done too.

I have said that far back in the fourth post.  :palm:

Good for you, I didn't see the 4th post, nor does it appear that this has been done.
