PAY ATTENTION: these procedures are dangerous and may be lethal for inexperienced personnel. However, I still can't get it to work. The turns-ratio may be set in the behavioral functions, but I chose to. Ever since I bought the Torres passive midrange control a number of years (>10) ago, and discovered that it used (as well as RC networks and a pot) an inexpensive miniature transformer to provide about a 1 H (I think) inductor, I've been fascinated with using passives to modify tone as well.
