Moreover, equipment that outputs > 110V 60Hz current is just too bulky and expensive for home use. A transformer takes 220V 50Hz input and produces 110V (or whatever other voltage it's designed for) 50Hz. There are also less expensive converters that produce various strange wave-forms at 110V. These latter devices should only be used to power things like heaters and light bulbs. I would expect a receiver to work fine on 50 Hz, with the possible exception of differing FM standards. In fact, many receivers can be modified for 220V operation directly -- check with the manufacturer. Whether your cassette deck will work with 50 Hz depends in large part on how its motor speed is controlled.
