first stop plugging speakers into this failed amp and grab a multimeter and check for DC on the outputs.
next if you don't have a "dim bulb tester" google that and make one.
also without knowing whether regular signal along with "the very loud buzz" is making it to the output we have to assume that this amp has an output or supply fault.
