And this!!!Hello Chris,
I just received word back that, yes, Rein Narma designed the "Fairchild 670"
in 1952. He is one of the founders of "xxx", and has since semi-retired.
Mr. Narma is still on the Board of Directors, and stops in from time to

I rewound some x-formers over the years, but have no replacement x-formers.
I have the U73 x-formers that s all...
