Mystery ? Transformer
Primary: 100v, 115v, 127v, 220v, 240v

(TP) 703010-167A
Mystery transformer. 18 wires come out of this beauty. We cannot figure out the primarys. Two or three secondaries are center tapped. One is multi-tapped. I only have a handful of these and no patience to wring out the wires. So you get a bargain price to figure it out. NSN: 5950-01-180-6726. Government database states these voltages:

• Primary: 100v, 115v, 127v, 220v, 240v
• Secondary: Sec. 1: 24v @ 1.25 amp,
Sec. 2: 46v @ 2.5 amp,
Sec. 3: 75v @ 3 amp,
