Tech nical data

Special features

Almost identical to the RS-B465, whose successor it is. Tech nically, all circuit boards and housing components are interchangeable with each other.

The "PXS" capacitors in the signal path have now reached the end of their life cycle, which is noticeable by bass loss, channel inequality and undifferentiated sound. Since these capacitors are also installed in the power supply, failures due to short circuits or hum disturbances due to loss of the screen action may also occur in the medium term. However, the originally very good sound quality can be restored by an expert revision.
