Ah, I expected you to use both primaries still.
To do that the primaries have to be kept in the same phase.
Thus the wire of Primary 2 that was common with Primary 1 has to be moved to the opposite end of Primary 1. The other end of Primary 2 now has to be moved to where the original common point was at the end of Primary 1.

eg S= start of winding, E = end of winding, 1 = pri one, 2 = pri two..

originally 230V  :-
S1111111111ES2222222222E

intended 115V :-

S11111111111E
S22222222222E

Hi John,

I thought that instead of 2 serial connected winds, for 110V supply to use
only 1 wind, so there is  no cross phase  problem there. Or am I missing
something?

Careful, I thought that you would need to reconnect BOTH wires because of
phase.

...clip...
Clock transformer has 2 winds rated for 110volts connected in series, so I
believe,
it's quite simple to re-solder one wire for one wind use for 110-120Vmains,
as in USA.
