Re: TDA 1200B AM/FM radio chip
It has always baffled me why manufacturers don't spend a few pence on a diode on the power input socket to protect against reversed polarity in supply... I just can't see that that tiny extra cost couldn't be accommodated... It's just about reasonable to expect Mr Average to check correct voltage from a wallwart - polarity is probably just a step too far for most people.
