120V to 160V ... can't be good for the tube live. The Tubelife PSU works with 120V however.

And Tubelife PSU has sweepable polar characteristics control, or it has only 3 positions?

This is picture of my open UM57, I found some components to be different from picture somewhere on the web, so this is maybe why they sounds different from piece to piece.
