Would need pictures to tell if that's the case. If the
transformer is open, then that will kill both channels. As far as I know, all the
EDI of that era was 2 to 7.6 volts as compared to 0 to 10. You're not going to find a "
drop in"
transformer, unless it is off another
unit. Just too many years out of production. But, from what I remember, pretty much any small 12 volt
transformer will do. There is a lot of useful information on this thread, if it is the same
unit. There was one "older" style that used pulse transformers but the board looked radically different.
