  • Notes

  • Stereo console with FM (Stereo) and AM radio and record player.  Standard DIN input sockets. The  turntable can operate on 50 or 60 Hz.  The units are configured for the Japanese market.

    This schematic is the same for model DPK86 and DPK305.

    Two sets of speakers are marked on the diagram: The first consists of two sets each consisting of a 20cm Woofer and a 6.5cm Tweeter. The second two sets each composed of a 20 cm Woofer, a 6.5 cm Mid-Range and a 6 cm Tweeter. There are no other indications, but it is conceivable that the DPK 86 model uses the 2-speaker system, while the DPK 305 uses the 3-speaker system.  Considering that they use the same schematic and there are no other differences.

    All transistor listed. Diodes listed only one per type.
