The following pinout shows jumpers and caps at the male yoke plug or internal in the yoke; not the chassis socket.
CT-100:
Pins 1 & 2 = Vertical
Pins 3 & 7 = Jumpered
Pins 5 & 8 = Horiz with Pin 4 Horiz windings center tap. Also a 270 Puf cap across one side of Horiz (pins 4 & 5) inside the yoke.

CTC-2B (21CT55):
Pins 1 & 2 = Vert, and pin 6 is also shorted to pin 1
Pins 3 & 7 = Jumpered
Pins 5 & 8 = Horiz with pin 4 Horiz windings center tap. Also a 150 Puf cap across one side of Horiz (pins 4 & 5) inside the yoke.

CTC-4:
Same pinout & cap value as CTC-2B
_________________________
CTC-5:
Same pinout as CTC-2B & CTC-4, only difference is cap across one side of Horiz in this one is 82 Puf.
