A 120VAC 60Hz transformer will be fine if the voltage is also reduced, as well as the frequency. It'll be able to work at 12VAC 6Hz with no problem. If the insulation can handle the extra voltage it'll also be fine with 240VAC at 120Hz, although there will be additional losses due to eddy and hysteresis, which will increase the off-load power consumption and heating.
Presumably you're using the transformer in fly-back mode, which is different to how it was designed to be used.
Which winding is connected to the 555 circuit?
Is it just single ended or push-pull?
Post a schematic.
