Im trying to use ordinary mic and line transformers in zero-field configurations and getting less than stellar results. it works but the performance is a little worse than using the transformer as they were intended. I think it is mostly an issue of me using completly the wrong parts. I have some ideas, but does anyone know the basics of selection criteria for this application? I know the core doesn't have to be as large, but it doesn't hurt if it is, right? what about primary inductance and trurns ratios?
