The manual describes this product very good. It has the basic things to know and also a more detailed look. Very well made!

An excellent document to assist in the repair of my old personal tape player. It includes full circuit diagrams and physical layout drawings and full instructions on disassembly and fault finding.
Well worth the meagre price.
