factory technician level - complete with board views :
( removing chassis from cabinet , only thing missing ) ;
on weekends , staff is not available so - be patient .
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.
Very good conversation, Pretty fast Service, wood do it again,
Have paid by Paypal, so i got the Service Manual online after 15 Min.
Very helpfully.
Greeting from Germany,
Hans
