Default LM1876 feedback cap Q.

I'm currently wiring up a LM1876. In principle I'm using the National datasheet scheme on page 6, "Auxiliary amplifier Application circuit. I'm a little puzzled on the feedback cap Ci with value 10uF from the feedbackloop to ground. Should this be a filmcap? at first I thought it should be an electrolitic, due to the value but at this point there is no DC. If it can be electrolitic I assume the - should be connected to ground. Is this correct?

Unfortunately I could not find to many "as built" schematics of the LM1876 (I did use the search)
better be indoubt untill you're sure

Try to use metalized film cap (a.k.a poly cap). You can use non polarised electrolytic cap as an alternative.
