Superb built quality consistent with Pioneer blue light era of the early 1970s. Face and knobs are outstanding and wood veneer cabinet is very durable versus vinyl veneer later in 1970s. It drives 6 ohm Koss speakers without breaking a sweat. If you are seeking a high quality, smaller footprint, ultra-reliable receiver with excellent radio reception (the Dolby era later on became obsolete anyway) you will be hard pressed to find an equal. With superb examples at $200 and very good ones closer to half that the quality and reliability is difficult to match with other manufacturers.



re: SX-424

I have a problem with the stereo light and the signal meter. If stereo is tune it do not moves and stereo light doesn't come. In AM the signal meter moves.
