Cylinder on mains adapter CD player

We have a quality old Sony personal CD player in good nick. However although works with battery, the power cable is irrepairable .On Ebay , we can get a used Sony replacement All the important number detail on the plug is identical (although ours made in Malaysia and Ebay one in China), and the end that goes into the player is identical . The only difference is that our old one has one of those small cylinders wrapped into the cable , and the new one doesnt . Google tells me the cylinder is something to do with interference , so logic says its there for a reason, but why wouldnt the new power cable need it to fit the same model machine? ps the cylinder cant physically be transferred to another cable ) The new cable is not cheap at £20 (scarcity value ) so any thoughts please on the chances it would work well with mine ?)

The cylinder is a ferrite core and is indeed to stop interference. The replacement adaptors may not need this as they may be a different design or possibly have an internal ferrite core, If you have a problem you can buy clip on ferrite cores on Amazon/Ebay.1

£20 sounds very steep for a power supply for a portable cd player.

Norman Castle - Agreed , I was shocked, but the only cheaper ones I could find for the model , were 6v against the 4.5 on ours. Our device according to the blurb on plug, is Sony AC-ES 455k 4.5v Imput AC230 v 50Hz 4w, Output DC4.5v 500 mA Made in Malaysia 501-41 Sony Corporation . Googling that gives me 4 choices and this secondhand one is the same in all but the ferrite thing and the number above where it says Sony Corporation. The price is 'offers' and I was thinking I might get it for a fiver under the asking price ? I wouldnt have thought there would be many of the exact cables available , hence I suppose the seller calls the market?https://www.ebay.co.uk/itm/303502630257?ul_noapp=true0 -
You need 4.5v, min 500mA, positive centre pin with the right size plug.

The important bits are 4.5v, at least 500mA and that the end fits the player. The lack of ferrite core won't really make a difference.
If you want to avoid the many cheap Chinese adapters which might or might not work, here's a genuine Sony very similar one for £9:-

You might need to check the size of the connector but my guess would be that it will fit.

Wow, thanks everyone ,even a choice ! I would never have had enough knowhow about such things to dare to investigate alternatives to what looked identical ! Grateful for both links, but being risk averse and having seen far too many shares on FB of Chinese plug overheating and causing fires, Im favouring the Sony option just for peace of mind ! Regarding the connector Chris W , are we talking the colour of the jack plug bit? (Im under the possibly flawed impression that colour denotes particular size?)0

I would have thought it likely that model numbers E455K and E455D have the same jack plugs but I don't actually know.

Mm I thought I might have been wrong, a colour would have been just too easy lol! How difficult would it be for the seller to measure with a ruler/tape , are the differences so minimal that its too hard to be sure of accuracy ? I can get him to photograph the jack plug end on if the inside might be different if thats a likely thing.
Probably go ahead anyway , I forget the one youve found is a hell of a lot cheaper than £20 , so not the end of the world if wrong .0 -
Secondly , if we had to purchase a new ferrite core , how would we get it onto the cable -- the old one is sort of threaded through and around the cable, it can be slid up and down, but there doesnt appear to be a way of opening it up to detach it from the cable and of course it cant be slid off either end .

Thanks Stevie . Perfect if we need to go that direction at the end of the day .0
