Ever watch an ART-13 tune itself?

Heh, I have, about 20 years after it first came out. That, and
I used to align R-391s...which were much more fun to watch.
ADA had one commercial Collins Autotune transmitter for
about two years, three racks wide, all the Autotune rotary
power came from a single quarter-horsepower reversible
motor. Fastest-reversing motor I'd seen up to 1953.
