Actually, as I remember, it was more like 1200 man-hours of maintenance
per hour of flying time. I worked on them as a Bomb-Navigation Systems
Mechanic. You are right about the vacuum tubes. They were
sub-miniature tubes. The circuit boards were coated with epoxy. What a
mess to work on.

In 1964/65 I was stationed at Kelly, AFB in San Antonio... the USAF's
bomber hospital. My wife and I lived in a small apartment over our
landlord's garage on the approach to the runway. We were rudely
awakened on many mornings by the sound of B-52s and B-58s (which howl
like a banshee).
Yuck!! The B-58 was a bomb all by itself. It required more than ten
hours of maintenance for evey hour of flight, mostly because all the
electronics was vacuun tube.
We had the hulk of one at Little Rock AFB for firefighter training.
I think there's one at the Pima Air Museum in Tucson.
