200 Micro Farrad cap, 200 vdc electrolitic type.Anything matching that with an equal or higher voltage rating will solve that problem. Try a local electronics suplier they may have one sitting on the shelf ( so might I actualy )
The AVR unit is a different matter, if its toasted its probaly not servicable.

I need to go back and rethink the AVR project, need something simple that still produces good results ( %5 )
