I bought a Fostex 380S in the late 90s at just about the time I quit playing and recording. It has been sitting around for almost two decades. I just went in and replaced the drive belt. It worked for a couple days. As of today, though, the play function stopped working. Pressing play brings stillness, and then every light on the display comes on. Fast forward and rewind still work. Before going back inside, does anyone have similar experience, or knowledge of this failure? Is it my new belt gone bad?
