Hi
I’m considering a Recap for my Linn Linto phono stage.
Attached is a screenshot of the main PCB.
1. Other than the 14 Capacitors in the attached picture, are there any other Capacitors that need changing ?
2. I read in the various forum, various preferences of Capacitors types that are worthy. Is it that different types are good for different phono stages ?
Which brand/type regardless of budget will give the best performance ?
3. Which internet shop is reliable and sells only original parts ?

You need recapping only if the thing is over a decade or mpre ago. Why do you suspect you need it?
If you are dying to change capacitors, the big ones inside the power supply are the items most affected by time and use. They get stressed and hot.
Replacing the blue Panasonic caps on the PCB seems a bit unnecessary, but if you really want to, go ahead. Please replace with something that has 105C tempature rating. That greatly helps with longevity.
I count 90+ capacitors on that board. What makes the blue ones the target of your interest?

I find buying 85 C electrolytic capacitors with >3000 hours service life from panasonic, nichicon, rubicon, vishay, kemet, provides entirely enough quality and service life. I've replaced >400 in amps & organs since 2008 retirement, none needed replacing again. Compared with the **** from the front of store bins at TV parts stores I had to use before the debit card was invented when distributors wouldn't sell to individuals.
Farnell operates in most countries whereever you are, sells real authorized parts. Digikey & Mouser are on 3 continents. Digikey doesn't discount caps past shelf life. I've gotten 10 year old caps from them at full price. Caps past shelf life have to be recharged (reformed) with DC voltage before use. Reichelt in GER has a reputation, I haven't used them. Digikey & farnell will show the hours service life in the e-cap selector table if you request it. Mouser makes you download each datasheet & read it. I buy very infrequently from mouser.
I find some kinds of small electrolytic caps go off value before the main rail caps. If you only have a cap meter, >20 % high in value is a bad sign. ESR meter is a better test, but the Peak is ~$120, doesn't pay off in one project.

Personally, I would use a mix of 84/105C parts depending on the usage - for power supply bulk filtering, especially if it is an SMPS, I go with the 105C parts. Also if they are located near heat producing components - the additional cost is really not that much.
On thing to be aware of though, is that the value of new modern capacitors tends to be on the low side of the tolerance range where the initial value of older (60's, 70's, early 80's) capacitors was typically at or above the marked value. In capacitance sensitive circuits this can make a difference and for bulk filtering use I select replacements at around 150% of the original value.

To answer your original question, the ones you marked I would replace just to be safe - especially with the 2001 vintage of the equipment. The two sets of four on the right of the picture are filters for switching supplies and should be low ESR parts designed for that usage. The other electrolytics are tantalum and have a 50v rating; they, along with any others, should be perfectly fine as is.
