Where can I download the coil program?

What is the copper size for the coils?
We used 2,5mm 4mm and 6mm tube.

Do you know any source for ATC capacitors?
Those are hard to find. If you find a source, please share! Cornell Dubilier are a good alternative.

Can the filter handle 1500W?
The filter is designed for 1kW level. The limitation is the current flow true the C's. If you have C's that can handle more current or is you place more C's in parallel it can be handle more power. But we didn't tested this!
