The internal structure is most likely Mylar and certainly not organic as an FYI. 
Speaker hum problem - need help
Bad or going bad power supply cap? Would it not do exactly what we hear here......

No history with that. Sorry

A quick search shows that most, including Parts Connextion, lists them as PIO caps. However, Jimmy's Junkyard capacitor thread lists them as Mylar.

I am not sure Duelund claims or ever claimed paper and no plastic, but many of us assumed that as did reviewers. They may have some oil, but certainly not impregnated in the plastic stuff.None of this takes away from the sound, but I do find it in...

Not tubes for your speaker. Ghent is affordable and the trial period makes it risk free and fun.The others may be out of your budget. Keep an eye out for used ones.

Some interesting information is coming out on the very good Duelund CAST caps. I have seen pictures of one cut in half and it is pretty interesting what is inside. They contain lots of a plastic type substance and no paper or oil. Ya, you are read...

One other thing to consider. Replacing caps on a circuit board is more work. It can be a lot more work if space is tight, the board is cheap, the board has to be removed, there are small resistors in close proximity.........It can be tricky and as...

Salectric is right. If you are certain you have the right position and they are not power supply caps, then replace them. If they are output caps, then no need for that value and a 1 uf will be fine. I replaced the 100uf output caps in my Sony NS ...
