Multicomp pro MJ-14SR - it's the multi comp version of the mini Lumberg jacks they seem to have stopped making.

if it was a bit of a difference I would understand, CPC seem to be aimed at small volume orders more, but it's crazy difference, and not with discount as it comes down! I'ld buy from CPC but they don't have the Lumberg mono jacks I need
