The latest update to LTSpice seems to have a bad bug. Every time it saves a file, it replaces the coils with some transformer not connected. More if I figure out what is going on.
Old schematics. Used the "default" coil and only had a value set. I think they may have changed the default. Now I need to go look up to see which of their coils is an air-core.
Selected a coilcraft with high Ipk (12A) , low ESR. Guess it is an air. Pops back into circuit, so it seems they changed the default. As their intended use is for switching supply designs, it makes sense their default would be iron core.
Somehow I would up with an extra symbol in the top directory it was using rather than the one in the symbol directory. Killed it and all is well. I have no idea where it came from.
