Bought new 2 years ago, now died totally.
Date? 2007 on the pcb overlays but Schuko mainland Europe mains plug
with a 2014 moulding date.
Firstly that line-plug set in an "clamshell" adaptor for the UK , with L
& N swapped over, sprung brass earth used for "earth bond" continuity .
A break in the intended neutral wire somewhere, I originally suspected a
dodgey adaptor. I have removed the cable and break is not at the
so-called "strain relief" grommet. I'll hack into the cable , to
find&inspect the break before replacing the cable, anyone seen the
likes? PbF soldering to the "euro" plug pins or tin-pest "tinning" failure ?
No obvious overheating of the pins in the adaptor or casing or cable sleeve.
The internal 20mm 10 amp fuse & holder surprisingly looked healthy
considering the yokes of the holder were only just making contact.
Is it asking too much for 20mm format to carry 10 amps reliably?
