These are the new Duelund CAST bypass capacitors, made at the newly revamped Duelund Factory. Now fully equipped with the Jensen winding and impregnation machines. The paper separating the foils are vacuum impregnated in a deep vacuum 100 times lower, than what was possible at the old factory.

The JDM bypass capacitor made it clear that with the new equipoment a better performing bypass capacitor was possible.
These new CAST bypass capacitors are even more refinde sounding.

Duelund's bypass capacitors are specially designed to be put in parallel with coupling and crossover capacitors. Offering a much-increased performance without changing the total capacitance or crossover points. Available in 2 versions - The Pure Silver Foil Bypass capacitor creates more depth and gives an all-around clean up without becoming harsh or untrue. The Tinned Copper version offers great detail and dynamics.

The outer lead out, closest to the edge of the capacitor, is connected to the outer foil and as such should be connected to the lowest impedance path to ground.
