    The third amp in 3 days all requiring attention to quarter inch sockets of
    one sort or another.
    Can anyone put a generic or maker's name to this compact axial type

    no info of any sort on the socket.
    This one from an Ashdown effects return with dodgy bypass switch.
    There are 2 places in the plastic body that drilling through coincides with
    holes in the metalwork almost as though designed to wrap some silicone
    rubber cordage (blue in pics) around the switches to increase the closure
    force, located in place by curves in the contact parts. Then cleaning the
    contacts.
    Tip contact to the left and ring contact at bottom of first image.

    Incidently my test for whether such bypass switches need attention , even
    before dismantling the amp.
    Take one cocktail stick/toothpick . Hold at one end between thumb and index
    finger and poke the other end in the socket - if the contact breaks before
    the cocktail stick breaks ,about 150 gms over length of 65mm.

    It is AIUI originally a Switchcraft pattern but is very widely copied by Asian
    suppliers. JAE ?? comes to mind from the dark recesses of my mind.
