OP
hubsy
update.
testing class 1 smps all from the same source.
All had earth to outer barrel connection, Except one tested yesterday.
failed it and replaced it.
took it apart and sure enough, one of the soldered lugs have parted company from the circuit board.
resoldered and its now working correctly. scrapped it because had to cut the case off.
btw I am a competent electronic electrician.
