Superscope TDR-830: very nice, but missing a vital ingredient

This Superscope TDR-830 8 track recorder was sent to me several months ago by a viewer called Tom. I seem to remember it making strange noises when I first tested it, but when I started the video it wasn't doing much at all. I had to resolve several problems, one of which was of my own making, but would this almost 50 year old machine behave in the end? Outro music: Calvary by TrackTribe
