Speaker binding posts with plastic covers


My Krell amplifier has speaker binding posts with the clear plastic covers. Apparently these are for EU safety requirements. I want to use spade connectors and have no idea how to open these covers. I’ve wrestled with them but they don’t budge. I don’t even know whether they unscrew or pull out or whether there is some other method at play. Does anyone have experience with these?

Now that I see how they operate, I'm impressed. It's actually quite clever and secure.

well, considering that they were 'frozen', it's a good thing you asked/solved it before throwing the Krell in the bin!!!!

happy listening.

Thank you, thank you, for posting that diagram. That was exactly the thing confounding me most...

You're welcome! I'm glad to know that everything worked out fine, my Coda CSiB uses the exact same type of binding posts and I totally agree with you, it's a quite clever design indeed! 👍
