Good afternoon, I request the help to be able to change the heads of my cassette that for the years of use are worn out, so fidelity was lost when playing any cassette in both (deck A and deck B), if anyone knows the model or The features to replace them, please. And if it is a particular brand that provides this piece. So I can search better in my locality or on the Internet, without fear of being wrong. I searched the Internet by deck model without getting results. I am not an expert, but I would not like to use any head that could merit the quality of the equipment. The deck in question can play normal tapes, chrome and metal, includes Dolby B and C Annex the images, first Deck A and the second of Deck B. Sorry for the excess brightness in the images .
