Caps Pulling up Skirts

[ToadMeister]

Oh these axial ladies, always laying on their side.

Do I have a couple hot ones?

I have a few smaller size capacitors in my ~40yr old amp and the problem with them is the lamination, or plastic skirt on them appears to have slid down by a few mm's.
Almost the appearance on one end like puckering up lips, with a raised skirt on the other end.

These caps seem bad, but then again, it's only a tease.

Anyone familiar with this?

A picture would help....

Was thinking just that, but duty, the cruel master beckons. (have to go to work shortly)

Will try to do that later after work if I can find my card reader.

Caps are aluminum cans, with a thin shrink plastic sleeve on which to print stuff.  Heat in the environment over time shrinks the plastic sleeve, so it withdraws like gums from bad teeth.  it is not necessarily a sign of failure.

It doesn't really look serious, other than the plastic skin has moved slightly on a few of them..
