Indeed, adding these USB and radio modules helps to save and renew older devices. Thanks for sharing.

Albert, perhaps you do not observe these problems due to some differences. Surges are mainly observed in electrical grids based on poles (outdoor distribution). Perhaps in your country, the utility uses mostly underground distribution. Also, some countries have more incidence than others, like my country. Brazil is the country with the majority of lightning bolt incidences in the world: about 70 million a year. Ultimately, lightning bolts are more frequent in rural areas.

All LED driver have MOV connected across line before bridge rectifier. I have repaired few LED drivers by just replacing fusible resistance and MOV, which got damaged by surge and they saved the rest of the circuit coponents.MOV used - 07D511k.
