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)
