Can you recal how the fuse is fitted to the transformer?

I've just bought a new Dash Cam; I so wish that was Fisher-Price :).

The machines in which the mains transformer failed were made in the UK and Europe under licence by the J2T venture and I believe the afflicted TX was of German origin (TFK?). Your HR-D120 probably has a Made In Japan sticker on it, if so the TX will most likely be of Tamradio manufacture and I don't recall ever having to replace one.

I always wondered if failure was due to the voltage difference between the UK and Europe. A failed TX was always replaced but I have temporarily shorted out the thermal fuse to see if the windings were faulty. Some worked OK running cool, some began cooking after just a few seconds or minutes.
