Good gravy.What a resource.I was told by the friendly folks at RYM to get ahold of you.I was going to email you and beg for info.Does one simply rearrange the taps?I see red wires going from one terminal to another.I'm to switch these around?To add or subtract voltage?OK.First I'll see what the voltage is,and then I can maybe figure out myself on where to put them...The oscilloscope-I'm not really proficient with one,but I have access to one,and a whiz who knows how to use it.I'll do my homework before I will ask any more questions,but I'm NOT used to these machines-They sure are neat ,though.Thanks Dan,Doug
