This appears to be a 2:3 step-up transformer. (1.66)(1.67)(1.65)(1.67)
There are substantial differences between early and late.
In both cases, there are two windings: a large diamater winding and a small diameter winding.
The larger diameter winding is my wire colors yellow - black.
There are two capacitors, one across the primary and one across the secondary. The values are 25 +/- 10% and 100 +/- 3%.
The 'modern' schematic gives designators C112 (primary) and C113 (secondary).
Yellow - black: 22.4
Green - orange: 13.5
Yellow - black: 22.9
Green - orange: 13.7
Yellow - black: 21.1
Green - orange: 12.8
This is the transformer that spun in the can and detached all the wires.
There are two windings: a large diamater winding and a small diameter winding. The smaller is centertapped
but the tap is not brought outside the can. There appears to be a terminal for it and there may have been a wire soldered
to it at one time but there was nothing when I got the radio.
A poor resolution schematic from an early manual shows the single capacitor on the primary. It measures about 100 pf.
The original wire colors appear to be red - blue with a capacitor and black and green without a capacitor.
Yellow - black: 24.6
Green - orange: 14.5
The transformer appears the same as for the 4th radio except there does not appear to be a centertapped winding and the single cap is on the opposite side of the transformer if the wire colors are to be believed.
Yellow - black: 21.8 or 22.8 (two different meters)
Green - orange: 13.63
