Transformer resistance tables for T2

T2 is the second IF transformer. It connects the first IF amp (V5) to the second IF amp (V6).

The examples of this part that I examined all seemed to have different wire colors. When I rewired them, I used my own colors. I used the same colors for each one I rewired.

The schematic snippit shows the interior parts of T2 (C106 and C107) and the 8 wires coming out of the can with my selected wire colors.

The red wire goes between a capacitor inside the can (C106) and the junction of C28 and R18 which is the source of B+ for V5 plate. It carries no DC current. The brown wire goes to SW9-2 which provides B+.
