I am in trouble. I bought my wife a sony mz n510 type s. For christmas And then discovered our cd/cassette player had no connectors, the only outlets are speaker wires. My wifes only reason for wanting a md was to record her cassette tapes on to it . please is there any way to record cassettes on to it. If there is not I am dead.. If there is a way please explain in simple terms, I am oldish ha ha. Thanks Sholto
