beomaster224: I missed the 2333 in the aforementioned
manual the first time, but having another look, it's all there on page
2...
And from what I see (I don't have that much expertise in circuitry diagrams, though) I think the 2333
IS able
to work on 230V. At least, the diagram shows wiring with 2x60V (=120V,
US mains) and 2x110V with additional (?) 2x10V which I guess sums up to
240V (which would represent the European upper voltage boundary of
240V).
Yes, but the way I interpret it, the schematics on
the primary side just show two alternates, and don't mean every
transformer has both of them. Also, I only see four solder lugs on the
primary side of the transformer in your pic and so I believe it only has
two non-tapped windings, not four (nor six, if all the alternatives
were available).
The more complete BM6500 service manual shows the
transformer wirings, and the Euro models apparently can be rewired for
220/240/110/130V, while the US 120V model is fixed to one voltage only
and so is the 100V model (Japan, I guess). They have different part numbers for the transformer as well.
But
I'm only working from the schematic and Martin has seen a lot more of
these, so I'm not going to argue with him - if it is possible, then
great

I believe the microcomputer uses the "50/60
Hz" line for timekeeping, but it apparently autodetects the frequency,
so that shouldn't be a problem.
