Layout/lead dress question

[pine]

Is it bad to have the cans of your power supply filter caps touch one another? I added some in parallel to my existing caps to change the value, and due to space considerations, they are lying on top of the original caps. I haven't noticed anything out of sorts but I would like to run it by you guys before I finalize things. Thanks in advance.

Shouldn't be any problem. Most E caps have a plastic sleeve and besides that, the can is the negative side of the cap so it should hurt anything if the metal touched the metal of another can.

Filter caps touching can be an issue in totem pole arrangements. because one cap has half the supply voltage on it's outer case. Over time it can rub against it's neighbor and short. A little silicon prevents the problem.
