YB 400 Ferrite Antenna Question
 

Recently bought one of these used. All works fine except the antenna was
broken in half, now fixed, and the four leads (red/white/black/green) were
torn from their solder pads.
Would anyone know the proper connection for these leads. I do have the
schematic but nothing is indicated on it.
Thanks in advance. Oh, I did try the Google group already to no avail.
