Removing push-in spring clips and replacing with binding posts (Speakers)

[martian sunrise]

Hi All,

I have a pair of Tannoy Eatons. One speaker has knackered spring clips, with (cut off) wires soldered to the stumps.

I would like to remove them and replace them with some good binding posts, but don't really know what I am doing.

Do I remove the driver, then go in from the front to undo the panel with the spring clips? I assume then I need to unsolder the wires off the spring clips and then put the posts in and solder the wires back on.

Am I on the right track? An advice is welcome, better still, if there is anyone nearby that could help, I would be massively grateful.

Rich.

I replaced the spring clips on my Tannoy Devon speakers. Used gold plated binding posts from Maplin (not sure if they still stock them). The drive unit had to be removed from the cabinet.

These might do, certainly cheaper that what I paid in Maplin. http://www.ebay.co.uk/itm/2x-Amplifier-Speak-Terminal-Binding-Post-Banana-Plug-Connector-Gold-Plated-FG-/371804227925

These are a bit like the origainal clips, but I guess they will take a larger cable http://www.ebay.co.uk/itm/2PCS-Gold-Plated-Brass-Speaker-Binding-Post-Spring-Loaded-Press-APM-Terminal-/201553037455

Would think that would be the way. Geoff would certainly know. Sure he will be around later. One of our Tannoy men.:)

I've only owned two pairs of 12" Silvers, two pairs of 12" Monitor Golds and one pair of HPD 315's, lol! Sadly, no Eatons

Looking at pics on the web, Eatons appear to have either sping clips or binding posts.


This Eaton appears to have the same spring clips that my Devons had http://www.canuckaudiomart.com/details/649330855-tannoy-10in-hpd-eaton-speakers/images/1444145/

They were easy to replace with binding posts.

i did say one ;) geoffs had em all several times i think lol. but think your rioght and you will likely get them out via driver hole. i like speakers with a back that comes off

Yes. You remove the drive unit to access the rear terminal plate. You'll have to pull the sponge wadding about a bit to reach the securing screws. Once the plate is free, if there's enough slack in the wiring, you can either poke it through the back opening to work on or do it from the front. I doubt you'd need to undo the tweeter control panel on the front to gain some slack, but that is also easy, should you need to. If necessary, the wadding can be secured back in place with contact adhesive.

I'd opt for the first terminals shown above: http://www.ebay.co.uk/itm/2x-Amplifier-Speak-Terminal-Binding-Post-Banana-Plug-Connector-Gold-Plated-FG-/371804227925?clk_rvr_id=1180053788450&afsrc=1&rmvSB=true

They are sturdy, fit properly, are of good quality and will accept bare wires and 4mm banana plugs.

This job is well worth doing as the original spring terminals are a real pain!

They are the same type.

If you've not tried a pair of Eatons, you've missed a treat. To me, they sound notably nicer than the HPD315 Devons and Cheviots, which I've also owned. I've had five pairs of Eatons. Should get another set really. :)

Well, I'm not really a "Tannoy man" I might have to be as I get older, they can go pretty loud! If a pair of Eatons turned up at a lowish price (not that likely these days), I might be tempted.

Just one point, I was able to change the spring clips for the binding posts without any soldering. I think I had to pull away the sponge wadding a bit, as you say.

Great. Thanks for the responses. I have a couple of pairs of Michell binding posts, so I'll have a crack at it. Nothing like on the job training.

Is there anything else that I should do while I am in there?

I think the Maplin binding posts that I bought are much like the Mitchell ones.

Perhaps use a vacuum cleaner to remove any debris inside if there is any.

I found the HPD 315's a bit heavy when removing them, just be a bit careful not to drop them.

One thing I forgot, the drive unit is connected by means of a 4 pin plug whose contacts can get dirty / corroded, causing intermittent connection.

I put a little Servisol contact cleaner/ lubricant on the pins, inserted the plug and took it out a few times, wiped the pins with a cloth, then a little more Servisol, no further problems.

There may be better ways to cure this, but this way worked for me. High quality plugs and sockets (probably better than the originals) are available.
