non polarized filter caps?

[jzucker]

I replaced the bias cap in my super reverb with a non-polarized version because that's all I had laying around. It was a 47uf 100v cap. I ordered some polarized caps for replacement but is it safe to use a non polarized cap in the bias supply of an amp?

...yes, as long as the "working voltage" isn't exceeded.

Thanks.

Yes absolutely. In some ways it may be preferable. The reason you don't see it much is because of the size and expense of the large non-polarized caps (high value polarized caps can be made much smaller than equally high value non-polarized caps).

In some high-end hi-fi gear you'll see only non-pol capacitors in the power supply sections. Whether it has a performance advantage is of some conjecture.
