Before we both get pointed emails, I ain't Jeff.
That was Katz Broadcasting when we built Birmingham and Atlanta. Your Dad and Soft - Hearted John (Marino, lately of the NAB) designed the Atlanta setup on a couple of napkins in New York one evening after a meeting. PR&E supplied the furniture, consoles, Tomcats,and vendor gear. It was a showplace. And the guy who engraved all the switch tops I bet STILL cusses me, cos I had them make all the ON buttons yellow instead of red. The ABX even survived a coke down the innards, with only one piece of the backplane having to be replaced. I could have repaired it, but it was only three months old, I didn't want a bunch of buss bar over the eroded places in the runs. And after replacing it, I understood how the boards were so quiet ansd stable. You could arc weld with the power supply iof you wanted.
I suspect if the FAA had left them alone, Porsche would of gotten more power out of their motor than Teledyne. Supposedly an FAA guy told one of the German engineers that fater all, Avco Lycoming had produced 50 thousand opposed engined over the years. To which the German replied, "Ve built that many last year,."
