I don't know that I see anything "wrong" with the two different designs. One uses a cap to filter the negative leg of the power. One cost a little more but so does the set.
When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
