I'm about to buy a British radio for cheap from Craigslist, it's wired for their standard still so 220V and I presume 50Cps?

Will I encounter any problems with the transformer (i.e. overheating) if I use a step-up converter to get 220V from 120? Or am I going to have to replace the entire transformer with one that will do 120V/60Cps?

It should be fine.I have a radio with a 25hz transformer that barely gets warm.I would think that a 50hz one will be the same.

Sounds good to me! Thanks.

BTW, is that a Varg avatar?

There will be zero issues using a 50Hz xfmr on a 60Hz system. In fact, it'll run cooler.

The lower the frequency the beefier the xfmr has to be to handle a certain amount of current.

Not a problem unless there is also a clock. Then it will run fast on 60 cycles.

You can use an isolation transformer to step up to 220 volts. Wire the secondary in series with primary to step up voltage. Less expensive than a 120 to 220 volt transformer.

There is no problem for a transformer designed for 50 Hz to be used in 60 Hz.
The flux in the core will be inversely proportional to the the frequency so in will be about 20% less in 60 Hz than in 50.
In the other hand there will be slightly more losses because of the increased frequency but in the end the transformer will work cooler.
I live in a country with 50 Hz and for us the problem is inverse and very worse sometimes specially with transformers designed to the limit ( too high induction).
Use it with confidence.
