One good used vintage chasis jack as shown.

HAS NO PUSH BUTTON, JUST THE RECESSED ONE,  SO IT WILL NOT RELEASE WITHOUT INSERTING A SMALL SCREW DRIVER ETC

ONLY WHAT IS SHOWN IS INCLUDED

If you already did not know, you can take out the insert and use to repair old EV microphones or UA-3-11 plugs (see picts) if you have a mic or cable with worn out connector innards!

Nice gold plated pins!

Note these are NOT XLR, these are the older larger hard to find version.
