Notes
Almost identical in construction to the RS-B465, whose successor it is. Technically all boards and case components are interchangeable.
The "PXS" capacitors in the signal path have reached the end of their life cycle by now, which is noticeable by bass loss, channel imbalance and undifferentiated sound. Since these capacitors are also installed in the power supply, in the medium term there may also be failures due to short circuits or hum disturbances due to loss of filter efficiency. However, the original very good sound quality can be restored by a professional revision.
For your consideration Due to the age, the plastic elements in the drive become increasingly brittle and break, the pinions of the rewind motor burst open and slip off => irreparable.
