The 4mm banana plugs are actually RS. U.K. PAT.APP.
I have put them together but now cannot take them apart.
The round inner shaft is stuck in the plastic outer casing, under a hexagonal lip.
I had thought that if I squeezed the outer case, the hexagonal hole would deform and the shaft can be pushed out but I cannot get that to work.
There is a spring on the male input. Does that need to be pushed in?
It is frustrating!!!!
Thank you for any information.
