Offered is a Dynakit 70 Stereo. I know very little about this. The stereo system was left hooked up in a investment property I acquired. Seems it was kept in pretty good shape. It was still hooked up to speaker wires and a turntable when I found it. I cannot speak on its functionality. I did plug it in and all of the tubes lit up. With my lack of experience, you should figure it for parts or in need of repairs. Feel free to ask any questions and I will do my best to answer.
