+## Hardware description
+
+JS-910B is the designation for generic Chinese binding posts with 4mm banana socket connections for panel mounting.
+(example [AliExpress](https://fr.aliexpress.com/item/1005006406536395.html) link).

+
+The order in which all of the parts go is not 100% obvious until you have figured it out:
+* socket body
+* plastic insulating ring (hollow)
+* panel
+* shouldered plastic ring
+* metal washer
+* connection tab
+* tightening nut
+* locking nut

+
+## Panel mounting details
+
+The clever part of the design is the shouldered plastic ring: the shoulder goes through the panel hole, to ensure insulation between the metal body of the socket and the panel (essential in the case of a conductive panel!). The hollow ring goes on the front and covers whatever height of the shoulder protrudes through the panel hole (in case the panel is thinner than the height of the shoulder).
+
+:warning: *Of course this means that the panel must be drilled to the outer diameter of the shoulder (8mm).*
