George, I don't have a manual or a schematic, but I would think that is a regulated supply - if so, changing the transformer taps will only change the bulk voltage but should not change the output.
There may (or may not) be a pot in the regulator circuit that would change the output voltage. 73, Don W3FPR > -----Original Message----- > > I came into a cheap old Yaesu FP 107E power supply which works > fine, except for somewhat low voltage output.
