I have made a bigger DC filter for getting rid of the hum in big toroidal transformers. The pcb has 105 um copper and more than 1 cm wide traces. If the interest is big enough I will go ahead with a group buy. The diode package can handle 12 amps and 68000 uF/16 V caps will fit. This pcb is perfect for those who like it big.

The DCT02 has 6 amp diodes so this could be a practical limit but for 110 V countries this could be a bit low but since you can add more capacitance you will get a very good current capability plus that the diode chain can handle more. I have four diodes in series so the DC limit is also increased.
