How to avoid a electrolytic capacitor on a (audio) signal path?

It works well. But I'm still not happy because of the electrolytic capacitor I used in the signal path. My design was based on the reference design of THAT corporation: The capacitor above is a polarized type. The signal is not biased before. As far as I know, this is a bad use. I also verified my concerns with a simulation. If the signal really containts a negative DC (which this cap tries to avoid) the cap would/should fail or blow. So I want to replace it with a polarized type. However there is not really a good/small capacitor with such a high value, so I also would like to decrease its value. My circuit works with 10u and I cannot detect any cutoffs in the LF-Response. Still a big cap in the signal path. I cannot calculate properly the value of ...

How can I un-seize track nuts?

Is there anything (short of ordering another pair) I can do to release them? They're not stuck to the bike or anything like that, it's just that the grippy bit is supposed to spin independently of the hex bit. parts mechanical bolt share | improve this question asked Aug 19 at 13:52 Matthew 470 7 21 add a comment  |  up vote 3 down vote favorite I bought a set of these about 18 months ago now and for a little while they continued to work as they should but then now they're seized up.
