At first I thought there had been a mix up as I required the service manual for the cassette unit and the one supplied was for the CD unit. However when I scrolled further down I realised that both had been scanned together! This enabled me to dismantle and repair the cassette unit as intended and I also have a copy of the manual for both the CD and graphic equaliser units should I ever need them. Thanks very much for a great service.

Removing the Mechanism P.C. Board (Refer to Fig 10.)
Reference:The mechanism P.C. board can be removed without removal of the TRAMECHA assembly.
Note: Before disconnecting the flexible wire coming from the pickup from the connector, be sure to solder its shorting round. If the flexible wire is connected without soldering, it may cause breakdown of the pickup. 1. Solder the shorting round of the flexible wire connected with the mechanism P.C. board from the back of the mechanism assembly. 2. Disconnect the flexible wire from the connector CN601 on the mechanism P.C. board. 3. Remove the three screws C fastening the mechanism P.C. board. 4. Unsolder the two points of the part h and one point of the part i of the mechanism P.C. board. Then, remove the mechanism P.C. board upwards. Note: When reinstalling the mechanism P.C. board, connect the flexible wire coming from the pickup to the connector first and then remove the solder from the shorting round of the flexible cable.
