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! 👍

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

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

@jjss49
It does make me wonder what we ever did without the internet. 🙂

op - glad it worked out
usual a-gon ’make a mountain out of a moehill’ thread 😆🤣

@imhififan
Thank you, thank you, for posting that diagram. That was exactly the thing confounding me most. The cap had distinct parts and I wasn't sure where I should be applying pressure and so didn't want to apply too much pressure anywhere. Even with the diagram I still needed the pliers but at least I had more confidence about what I was doing.

@elliottbnewcombjr
Yes, you're right, I posted that photo of the 0765 because I thought it looked close enough. The amp literature doesn't say whether that is the exact connector Krell uses.
|
|
The channel-lock pliers have set the binding posts free, hallelujah hallelujah! Thanks, guys!
|
IF this goes on any longer, we will need a photo I think.

yes, you show a type, like mine and most, that does unscrew, and perhaps all the way out is a possibility, that would be the definition of dumb luck.
The link OP posted,
perhaps he just thought they all looked/worked the same, so he just posted that one, it just happened to be the rare one that does not unscrew.
IF this goes on any longer, we will need a photo I think.
|
BTW, if the top won't unscrew, maybe it's completely unscrewed! Try going clockwise and see if the top turns.
|
I hope this helps🙂

@rfprice
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.
|
@czarivey
Hmm, I must have misread something. Back to google.
Thanks.
|
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.
|
Don't use solder on speaker wire, for the same reason you don't use it on 200A electrical connections. It makes the wire brittle and is low conductivity. Always crimp.
|
I have similar situation and all I did is just busted plastic covers leaving metal screw caps. They don't hold up tight and within the time they will twist off.
Later I've replaced them with brass nuts
@curiousjim Deoxit F5 is specifically designed for switches and has lubricant. Any other Deoxit is also similar to penetrating oil
|
@rfprice
Now that you unscrewed them once, they should be good. And I don’t believe Deoxit has any lubricants in it.
All the best.
|
I sent an email to Krell yesterday. Their response: "They just unscrew." So I'll have to just unscrew them. I'll try some channel lock pliers. Do you think a blast of Deoxit might help loosen it?
|
people are telling you their experiences with their connectors that do unscrew, like mine .....
the type you posted DOES NOT unscrew. read the full description
another spade to banana adapter,
|
@rfprice
Those speaker posts look pretty much identical to the posts that came on the Parasound A21+ which I owned. If the same, just unscrew the cap as you would most binding posts. The only semi-difficult thing was figuring out how the spade connected, as it needs to be at a certain angle. Once figured out, it holds the spade exceptionally well.
I doubt Krell would adopt a different, less convenient binding post, at least for US sales.
|
There are Spade to Banana Adapters, here's one, must be others
|
These 5 way binding posts unscrew (the type you and others are thinking of),
- Accepts up to 8 AWG wire, banana plugs, forks, spades, and speaker pins
they are ’mini’ size, smaller outer diameter to fit where/when nearby obstacles prevent the larger outer diameter of standard ones.
not sure, your spades might be too large for these mini sized ones.
IF your speaker cables are expensive, the connectors on the Krell could be changed
|
|
They unscrew, but not the whole thing. The spade actually goes between the bracket looking portion. If you are trying to unscrew the entire thing you will break it. Just unscrew from the top of the connector. Should unscrew pretty easily,
|
just unscrew... they may be screwed on tight from the factory,,, work them loose with a firm but gentle hand
|
If all else fails, send an email to the manufacturer?
|
If they just unscrew, then they are very very tight. I'll get some heavy gloves and try again.
|
They aren't for personnel safety and not required by any code, they are to protect your amp from accidental shorting which is the most common cause of amp failure. (Everyone says "it just failed!!!").
Usually you can unscrew them with your fingers and put a spade in.

Can you not just unscrew them? I think the tabs on the two pieces of plastic 'covers' are there to facilitate that.
