Speaker binding posts with plastic covers

Most people won't agree, but I would probably just replace the binding posts.  I make my own binding posts but they are low mass and very similar to these from KLEI.

Hmm,  I must have misread something.  Back to google.

Thanks.

Again, assuming they are like the speaker posts on the A21+ I owned, they were the best speaker terminals I have used.  Without having to yank them vice tight like on other speakers posts on a handful of amps I have owned, they held my speaker spades with an iron grip.  Part of the plastic holds the spades so they will not rotate.  Once you see how the spade needs to fit into the terminal, you are good to go.

I hope this helps🙂

BTW, if the top won't unscrew, maybe it's completely unscrewed! Try going clockwise and see if the top turns.
