Continetal 220v radio used on 240v mains

[Radio Fixer]

Far harder to mount a bucking transformer in many sets. Much easier are those metal clad chassis mount resistors that can often be hidden away somewhere underneath.

Say 0.25A then that's only 5W for 20V. A 15W device would do fine. It is surprising how much cooler a mains Xformer can be with just 5W diverted from it.
