Celestion Ditton 25 and 44 Refurbs

Lol love the name! I bet it says "feeds wood" somewhere on the tin.

Thanks for the suggestion, I see Wilkos sell it for £1.75. I've already used some Colron teak oil but I'm not impressed with the results and it cost £10! I might redo them.

I ordered the capacitors this morning. Had to order them from 3 different places, so it's cost £15 delivery in total!

It took a lot longer than I expected, but finally finished!

What is the best glue to use when putting the drivers back? I'm pretty sure they were glued in before.

[walpurgis]

No No No! Never glue drivers in. Use clamps if you have to.

This sort of thing: http://www.ebay.co.uk/itm/BLACK-HEAV...Lt49loCMidH3pg

There are various types, including plastic ones if you don't want to mark the drivers.

Remember to use gaskets or foam tape to seal them in.


I think what you thought was glue was likely a sealing compound.

[madders]

Ah ok thanks! I was thinking about glue to seal them (they already have screws to hold them in place so I don't need clamps I don't think).

I'm glad I asked the question because I almost used some superglue!

So if I just get some foam tape from B&Q that should do the job?

is there not a rubber gasket?

[walpurgis]

This is perfect: http://www.ebay.co.uk/itm/5m-x-2mm-x...8AAOSwwpdW4pVW

You'll have to wait a couple of weeks for it to arrive from Hong Kong, but 2mm thickness is just right. In fact I've just bought a roll.

I sometimes buy black craft foam from hobby or art shops and cut gaskets from that. Trouble is, it normally only comes in A4 size. No good for 12 inch drivers.


Oh and if you have screw fixings for the drive units that'll be fine.

I just looked at the back of one of the woofers and there is a foam gasket - I didn't notice it before - it's pretty squashed. There is a faint ring of something round the hole though, so maybe it was sticky on both sides before.

Thanks! 99p is a bargain - I'm going to order some even if I don't need it right now. It must cost more than 99p to post it!

Scrape the old gasket off and carefully remove any sticky residue with a cloth damped with thinners or white spirit. Don't let it get on anything else.

I've been listening to these for the last couple of days. One speaker sounds excellent (the one I did first). I've realised there is a problem with the midrange driver in the other one. There is a fair amount of distortion at times. I've taken it out again to have a look and I guess there must be something wrong with the voice coil. It's rubbing when I push it in or out by hand. I'm not sure whether to attempt repairing it, or just look for a replacement on eBay.
