  Anyone has got a guess on these these phase of these trans? They were removed from yamaha pro active crossovers I believe there 600ohm 1200ohm Red brown low side blue purple high side. Brown and blue are possibly outer bobbin winding brown and red are the 600ohm and the blue and purps are the l200 ohms for the balanced conversion. Maybe I'm wrong with the impedance it was 15 years ago I pulled them out. They were the 600ohm output(neutrik) with a floating ground and solid state amp driving them on the low side if I remember right. Anyone know which should be the leading phase. My guess is red* and brown and purple* and blue help please. edit dcr of these 45 and 66 ohms thinking about it their probably 600-600 just one side is on the outer bobbin does that make sense? I need to get an oscilloscope I'm starting to get back into the groove of working on them again. I could so quickly work out if they are worth using.
