Default Caps on the chip with snubberized?

I built a snubberized PS for LM3875. Basically a dual bridge 3x4700uF per rail with the snubber stuff at the end. Do I still need the 1000uF caps at the V+ and V- on the chip?

The chip will be used in non-inverted mode.

EDIT---- I did another search/Sorry to waste your time.

Chipco, I just think that the right people have not seen you Q yet. Sometimes it takes a few days to get the answer you want. Sometimes I get used to recieving an answer in a few hours, but every once in a while,it takes a few days or even a week.

Anyway, I don't have your answer, but I am very interested in snubbers right now and would really like to see pics of what you have created so that I may begin to builg a visual of what they should look like.

Thanks chipco,
A real amateur enthusiast!

You may need ~470 uF bypass near the chip , if supply leads are long.If power supply leads are very short,these caps are not strictly necessarry.A 100nF ceramic caps are needed anyway.
