Please post any experiences about using mumetal or another type of irons in mic input transformers (1:10) shielding.
Can I use cooper or any combination of irons for 30dB shielding like mumetal ?.
Thanks !
Maybe I can try with M6 ...
Acceptable performance with simple iron 1.2mm, external psu. No noise tested with headphones. Tomorrow I will test in studio.
Dan, if you are after you PhD on shielding, I just stuck some referance books up at the tyransformer meta, namely Modern Magneticv something or otjher and Grossner.
