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.
Only catch with only using one winding is that it handles all the power. Running 110volts rather than 220, of course means that the current required doubles. If you connect both windings in parallel, each takes half the required current, and so they each carry the same load as if the two were in series on 220.
I don't know if the soviet designers were into using fusible links in transformers. Many UL/CSA transformers have a "weak" link in the windings, so over-current will open the primary. To keep UL and CSA happy, that link tends to be on the inside of the winding so that a consumer would not defeat the protection.
