[aprssig] Kenwood KPS-15 switching Power supply in Europe?

Does anyone in Europe with 220 mains use th eKenwood KPS-15
switching power supply?

I have one.  It is good for 23 amps at 120 VAC.  But I see no
nameplate indication that it can run from 220-240 and it does
not have the little voltage switch to select.

It also has no manual with it (or I lost it?).  Also the Kewnood
USA site does not have any manual that I can find.

So if someone has one of these in Europe, then it must also work
with 220 input.  I see inside that the fuse holder has two
ratings.  One for 120 and the other for 240.  I see also a
yellow jumper wire near the input caps that would seem to
possibly be the "switch" since the only difference between 120
VAC and 220 VAC on the input to most switchign supplies is
swithcing the caps into and out of voltage doubling mode.  They
still end up with the same almost 300 VDC to start with...?
Maybe...
