[Collins] Collins Power Transformer

[Dr. Gerald N. Johnson, electrical engineer]

The 1974 Rockwell manual (that I just downloaded from the CCA archives)
for the 516F-2 shows a dual primary transformer with different color
coding than the earlier transformer. Its 662-0249-010. So now we know of
three different transformer part numbers used, how many more were used?
Different part numbers for different ages and vendors? Did they require
changes in the chassis (I'd think the dual voltage would have required
an added terminal strip for the series/parallel wiring)? Do they all fit
the same bolt holes?
