Well 120 volts times 1.23 Amps is 147.6 Watts.
So get a transformer 300 to 500 Watts so it will run cool.
Sometimes bigger ones are as cheap as the small ones, just buy a good make not 'cheap' Chinese...

The mains transformers in the Magnavox was designed for 60Hz mains, not 50Hz mains, so will run hotter in the UK. Keep an eye on it when you first use it.
