I have just acquired a nice Denon audio amp, all 21 kg of it, for a nominal fee. The fault appeared to be that the input selection was stuck on 'CD'.
This was soon traced to a broken control on the front panel. This operates a slide switch mounted on the pre-amp PCB remotely via a steel tape in a plastic guide- a sort of Bowden cable.
I have managed to repair the item but could not locate such a thing with various suppliers, mainly because I don't know what it is called. Does anyone know what this item is known as?
