Good morning, folks:

    I have a question about dynamic speakers. I’ve got two sets that feature one—a 46-480 and a 48-482. Anyway, I noticed on both schematics that there are two coils for the audio path. There’s a V.C. and a B.C. I’m pretty certain that I’ve heard that V.C. stands for Voice Coil, but what about B.C.?

   

Side note, but I haven’t begun restoring the 48-482. That’s why I don’t include it on my signature.
