I am realizing that these big caps are quite expensive.

I am considering buy two smaller instead.

Pros - The pros are that they are most likely easier to fit then finding a big snap-in one that fit the exact hole spec. Two smaller are also much cheaper, almost half the price.

cons - What I have read on the net that two half the size could hibernate into feedback.

Any opinions on this matter ?

By experience that won't be a problem, only carefully placement is needed. Sometimes it could create hum or noise if placement is coming nearer to other components, so you need a lot of room to do that. But I'm questioning if its cheaper, 1 x 4700uF is normally lower in price equal to 2 x 2200uF from the same factory, and model.

Just to make sure, probably you allready know that to make 2x2200µ = 4400µ, you have to connect them parallel. (just thinking of placement on snap-in place)

On other hand two 10000µ/25V in series equals one 5000µ/50V.
