I have an Ion USB deck that takes input from tape decks via a
"1/8th jackplug". The Maplin catalogue has no such object.
Wikipedia says its the same as a 3.5mm jack, so I tried Maplins
one (Nikai brand) and it doesnt go into the recessed hole because
the body of the plug is slightly too fat, cant tell if the jack
itself will fit. Anybody know a specific product that would fit?

Try one molded on to a cable. These are often slimmer. The
ubiquitous "computer audio cable" is a 3.5mm stereo jack plug to 2 x
phono plugs. Quite likely you have one already. If the phonos don't
suit get adaptors or cut them off and solder something else on.
