Hi Dunc,
It was nice meeting you at the show. The Elcaset looks really interesting.
The DC2 is a really nice player but there are a couple of things you should be aware of with it. Firstly it uses the dreaded CX20084 motor controller chip, which is so easily destroyed by switch mode, reverse polarity or high voltage power supplies so I recommend using batteries only to power it.
Also it has the DD centre gear which usually cracks after 30 years or so. Basically the gear comprises a moulded plastic outer part, which is formed around a steel disc. Over time the plastic shrinks and the steel doesn't. so the plastic gear cracks. If you power it up and it makes a rhythmic mechanical clicking sound then that is a sign that the gear has cracked. It this happens, you can easily get a repair kit for it.
