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.
