What is the purpose of adding these components to the original circuit.
I have the same amp so should I do the same if this improves the output?
Also I would need to know the components as well.
I've never known the reason for it but I think it's for the protection circuit, judging from where it's connected.
Also, how much can I increase the 50v capacitor's capacity. Will 2200uf be ok when originals are 1000uf?
Why would you want to increase the capacitance? It will have no beneficial effects. Any improvement will be imaginary.
The Rev. K board has that circuit already.
About the capacitors. I tend to fit the largest capacitance, largest physical size, of good voltage rating replacement when I do replace them - this is for supply input and output rail only. All else I replace with like components.

The rail capacitors are weak, I want to replace. I want to use high ripple current capacitors like Panasonic FC but I want to confirm greater capacity vs greater ripple current? Which should I choose?
Should I trust Aliexpress? Cant find them anywhere else in small quantities.

I prefer the 1st due to cost difference.

Aliexpress will guarantee you get non-genuine articles. I like to use Nichicon VX. How did you determine they are weak? These amplifiers are not hard on the rail capacitors.
Also, a word about cost. Any money spent on a non-genuine part is wasted. Spend what a quality part that will work for years will cost, it's cheaper in the end.

You will need 50V parts for that location. Also, a 22mmx40mm part will be too large. 16mmx31.5mm is what you are looking for. 1000uf50V in 16x31.5 will be fine for many years if a quality part is used.
@jkrokenberger Capacity is showing 680uf on my Multimeter for a 1000uf capacitor
How about https://www.eecart.com/, I can order from them. Are they legit?

I've got exactly what you'd need on hand. I've not shipped to your country before but would be happy to if you want.
