Duelund inductors

The Duelund inductors is one of the highest quality coils available. The inductors are fully vacuum impregnated. The proprietary WPIO dielectricum is used which necessitates several days of impregnation under high pressure. This results in incredible damping properties, which offers a very high mechanical stability.
