The Inductor MigMa M1958 is made as replacement inductor for the classic passive Pultec EQP-1A filter. It is an over years, by ear improved air gapped high-efficiency core version filled in natural wax for a fast-changing temperature protection. The MigMa Series is
Mu-Metal housed in a magnetic annealed 0,7mm thick
Mu-Metal enclosure. The inductor cores are melted together by hand carefully. The pros of our special air gapped
Mu-Metal housed versions are:
- Very audiophile sound character due to the air gap
- Low resistance
- Shielding-Protection against electromagnetic influences
- Easily mountable onto every case by one M8 nut
- Color coded wires
- Slow warm up and temperature shock resistant due to the waxed inductor
- 150mH, 82mH, 68mH, 47mH, 33mH, 27mH, Output
