What determines which caps are in a kit?

Are the ones included just the most common that fail? Does a common problem cause a series of capacitors to fail or something?
 
Of course I'm just a newbie, but from what I here, any cap that is Electrolytic (has +/- placement) should be replaced as the dialectric inside the caps dries up over the years changing the capacitance of the cap. I have noticed some of the smaller value caps are not included in some of the kits but those may not be critical. I just replace all of them if I can't locate a premade kit for one.

I wonder that myself. When I order various caps from Mouser, I always get a couple extra of each value, so I have some spares when I do a cap kit, and a certain cap isn't included in the kit. I always like to replacer every cap on the board. Is there any reason why the entire thing shouldn't be recapped? Will those ones that you didn't cap eventually fail?
 
Cap kits SHOULD include every electrolytic capacitor, but most cap kits don't include the filter cap or the non-polarized capacitors because they rarely fail.

Now, some cap kits like the 20EZ cap kit don't include ALL the caps for some reason, which bothers me. I usually build my own cap kits so that I can replace them all.

Also, some "cap" kits will include other known problematic parts like resistors, etc...
 
For the classic monitors like Sanyo 20EZ, Electrohome G07, Wells 4600, etc. capkits were made up of the most common electrolytic capacitors that were failing _at the time_ kits were first being made. Now, 20 years later, many more electrolytics than what were first provided in the kits are failing from old age.

In some cases companies assembling the kits are going from kit lists from 20 years ago which may not include the ones that are now failing (the 20EZ kits come to mind).
 
What Ken said.

The lists in the Mouser Cap Lists thread are hopefully complete lists. I have found a couple omissions here and there, and have updated the lists when I found a "hole". Good example - the K4600 list was missing the caps for the interface board. I updated the list to include them.
 
Some versions of the 4900 have a 22uf 25v cap while other versions don't. Also, they have a 1uf 50v cap that bridges a diode that isn't listed....
