content: I don't think so. The 2mm "mini bananas" have the same raised portions on all sides. This just has a spring wire on one side.

content: Looks to me like a cheap variation of shrouded banana. I've seen them on old devices. I think modern shrouded banana is better. What's its diameter? Chances are it has some (limited) compatibility with normal bananas.PS oh, look on wikipedia:https://en.wikipedia.org/wiki/Banana_connector#Design. It explains different banana derivatives/variations.

content: Quote from: dorkshoei on January 29, 2021, 09:12:30 pmDifferent manufacturers have different methods of contact springing. That single side wire is favoured by Cliff in the UK, it's pretty good at making solid contact (no 'lantern' that can rotate on the barrel. try measuring the diameter of the solid barrel, I hopefully it's just under 2mm.

content: looks more like a pin plug with a spring. Pin plugs are different than mini bananas for what i've seen. If the pin is 0.080" in diameter or about 2.03mm then it is likely for the pin plug standard. It has been years (decades really) since I've seen any test equipment with pin plugs so consider that. On the other hand miniature banana plugs are designed around an 0.12" or 3.05mm OD on the pin.So I'm thinking Pin plug with some sort of spring. I've seen some cords with that type of connector without the springs, maybe the spring was broken off on those.

content: Quote from: dorkshoei on February 01, 2021, 05:23:52 amAnd how big including the spring? I agree it’s just a 2mm banana.Quote from: dorkshoei on January 29, 2021, 09:12:30 pmThere are many different systems for springiness in banana plugs, regardless of whether 4mm or 2mm: from a single spring, to bundles of wire, to several folded sheets (like the red one in your image), to the common louvered spring type, to even ones formed of nothing more than a rolled sheet of metal.
