I’ll hold off on using my side cutters until such times as I have acquired a replacement IC.
I’m in the UK and can’t find a reasonably priced source apart from the usual ‘lottery’ with Far Eastern suppliers?
As I wrote I have a CS8414 in stock. BTW you haven't replied my question why pin 6 has vanished into thin air.
* If the PCB gets heavily damaged when removing CS8412 then buying a replacement IC is not necessary anymore.

Your Post #9 above implied that I needed to change some other components even though the CS8414 is pin compatible.
This pre-amp PCB has several CS8412 ICs so I would be unsure of the impact if I only replaced one?
If there are more CS8412 then I would keep the cap and the resistor like they are. I did not know there are several CS8412 in that device as it is your device and you are the one giving useful information to us to solve your problem. Best would be if you could try to find the service manual and attach that to a post.
Availability of this IC in the EU is a difficult matter it seems. I think you should be glad if you can find one to replace a defective one. There are not many other easy options.

Like most owners of devices from Linn Products we can only dream of a schematic\circuit diagram being available! Some do escape into the public domain on rare occasions but I’ve been searching, usually in vain, for many, many years now!
I’m aware of the problems associated with counterfeit components so wondered if you could recommend a non-EU source for the IC I am looking for?
PM me if that’s more appropriate.
I stop recommending you my new/unused CS8414 in ESD safe container as my English seems incomprehensible to English speakers. The offer is retracted.
No I would not recommend a non EU source. I would search where least non original parts are sold.

Apologies for any misunderstandings which are attributable to my lack of experience!
Looks like I’ve come full circle and I’m back at my Post #1 in this Thread:-
“I'm looking to replace a CS8412-CS IC in a Linn AV5103 but am having the run-around in terms of finding a reasonably priced and trusted source for these.
One option I'm considering is to look for a scrap PCB, not necessarily Linn, that has one or more CS8412-CS ICs?”
This device has two CS8412-CS ICs, one of which is damaged! Replacing both with CS8414-CS ICs is problematic as changing the required SMD caps and resistors is beyond my skill set!

Advice: have it done by a skilled SMD DIYer. When the skills are insufficient to replace a resistor and a cap then replacing the IC itself is also not to be recommended.
Highest chance is to find new chips and not scrap PCB's as those are recycled. DIY people that read your text here are the ones that don't sell fake parts as they detest that in general. An easier denoised and less noise receiving text (to technical foreigners) would be:
"Looking for 2 pieces CS8412-CS so definitely the SMD version. 2 x CS8414 is also OK."

Thanks - of course I’ll take your advice about replacing the caps, resistors and the IC. Fortunately I know a skilled SMD DIYer that could do the work for me.
I also note your suggested ‘denoised’ text and hopefully that will help,

As the schematic is unknown I only can determine datasheet values so I advised on replacing the cap/resistor. when using the CS8414. First thing is to find 2 new chips and solder those. Then test.
Yes asking for 1 CS8412-CS while needing 2 is not good advertising. Finding scrap PCB's is a smaller chance than finding new ICs. Normal tech people keep spare parts not boards. Simple.
