Hi, I have some transformers C-cores, with various marks. Some cores have a blue dot, others red or white dots, and some have white inclined lines. I have some (unverified) information that cores with a red dot are for aviation devices (400Hz), with blue dot - max. B, and with white lines - ordinary Si-steel. But, I couldn`t find any reliable information about that. My question - has anybody any informations (links?!) on that (C-core marks)?
